What do I do with the unused input, output and I/O pins?
Pericom - Frequently Asked Questions (FAQs) - By Product Fam...Leave the unused output pins open; connect the unused sole input pins to Vcc or ground with a trace or a 10K to 100K resistors. For unused I/O pins, if it is set High-Z, connect it to Vcc or ground through a 10K to 100K resistor, or leave it open if it is active.
Related QuestionsHow should unused input and output pins be terminated?
Pericom - Frequently Asked Questions (FAQs) - By Product Fam...Input pins should never be left open or floating. The system may false trigger from noise if the inputs are left floating. It is recommended that all unused input pins be tied to a valid logic level using a resistor. The advantage of using pull-up or pull-down resistors is that they ensure a defined logic levels when the bus is floating. Typical resistor values range from 1 k-ohm to 10 k-ohms. Outputs may be left floating.

Related QuestionsWhat pins can I use for powering devices, a high signal, or for boolean input & output?
March 2005 - Posts - #region Coad's CodeThe TX & RX pins carry the standard serial signal, but the other pins can be used as high/low input/output pins. The output pins (4 DTR or 8 CTS), supply 5 to 15 volts (15v is proper RS-232 standard) when high and 0 to -15 volts when low. They only supply flea current so they're not meant to be used for powering any devices (like USB is designed for). However, they can be used as a reference voltage or for switching to one of the input pins for a high or low signal.
Related QuestionsCan the I/O pins on the HT46 series of MCUs be used as LCD drive pins?
Holtek Semiconductor - Cost-Effective A/D Type MCU SeriesThe pins on the HT46 series can be setup as either CMOS outputs or Schmitt trigger inputs, therefore they can be setup in three conditions which are, a high level output, a low level and as an input. By using an externally connected resistor divider on an I/O pin, when setup as an input, a voltage of VDD/2 can be generated. In this way a 3 common LCD configuration can be generated.

Related QuestionsHow can you mix both input and output measures?
HAPLR Index - FAQSome have criticized the HAPLR Index for including both input and output measures in the same index. They note that inputs like how much money is spent on materials or how many periodicals the library owns are different from outputs such as circulation per capita or turnover rate. Combining the two makes it possible to have a library with good inputs and poor outputs score moderately well.

The Revolutionary Service for Professional Traders and Amate...The PPI figure stands for Producer Price Index. Statisticians/economists like to differentiate between input costs of raw materials at the factory gate and the price of the part-finished or finished goods at the exit gate to see whether it is the raw material costs that are increasing PPI output prices or whether it is just manufacturers increasing their margins to the companies/suppliers they sell their good to.
Related QuestionsIs ADAT input/output necessary?
FAQ: Questiions about Soundcard and Audio Interface DriversTweak: If you have an Alesis ADAT multitrack you'd be mad not to get a card with an ADAT interface. But ADAT interfaces are found on more than multitracks. Most digital mixers have ADAT i/o. This interface connection allows the transmission and reception of 8 channels of audio in real time. So if you know a digital mixer is in your future you are wise to get an interface with ADAT i/o. If you plan to use an analog mixer you do not need ADAT i/o.
Related QuestionsDo I have to specify my unused pins as tristate or can I leave the default setting?
ECE 324/325 Lab Frequently Asked QuestionsYes! If you do not specify your unused pins to be tristate inputs you will likely encounter problems down the road, and you may damage the chip/board! The default setting has the unused pins driving ground as outputs. As you recall from class, if an output driving ground were connected to an output driving Vcc, a short would result and the hardware could be damaged. This could happen in the lab, so please specify the much safer tristate implementation for unused pins.
Related QuestionsShould unused pins on the MCS 251 Microcontroller, 8xC251SX, be tied to Vcc or Vss?
Intel(R) MCS(R) 251 Microcontroller Components - Hardware De...Ports 1, 2 and 3 have fixed internal s and are referred to as quasi-bi-directional ports. Port 0 is a true bi-directional port (open drain); i.e., the port pins float when configured as input pins. If port 0 is not used, it is advisable to terminate the pins with pull-up resistors or pull the pins to ground in order to avoid floating. All other control pins have internal pull-up resistors. It is up to the user to determine if unused pins require a pull down to Vss.

Related QuestionsHow do input/output instructions work on the Rabbit?
answers.htmThe Z80 and Z180 have special instructions (out, in) to perform I/O. Most Rabbit memory access instructions can be used to perform I/O by prefixing them with one of two prefixes. I/O to internal, on-chip, registers is indicated by the internal I/O prefix (ioi in assembly code). I/O to external devices uses an external I/O prefix (ioe in assembly code). This scheme makes I/O instructions more powerful and flexible. In addition, 16-bit I/O can be performed with a single instruction.

Related QuestionsWhat is the difference between "Input/Output", "Input-only", and "Output-only" transmitter cables?
MileHighWingsInput-only" cables transmit data only in one direction--from TX to computer. Most transmitter brands can use a single cable to carry data both ways, so, a single "Input/Output" cable is sufficient to support both 'Input' and 'Output PPM' modes. For example, Futaba uses 6-pin plug, in which one pin is 'Input PPM', another 'Output PPM' (there's also a ground and +V wires). Unfortunately, JR opted for 3.5mm mono plug, which only has 2 wires.
