Élan™SC310 Microcontroller Data Sheet

PREL IMINARY

Notes:

All Pull-Up and Pull-Down resistor requirements are specified in ohms.

1. This pin is an “alternate pin function select input” that is sampled at reset. This pin functions as a normal serial port output

after RESIN and IORESET are deasserted.

2. When this pin’s function is a DMA request input, it should be terminated with a pulldown resistor if not connected to an external

device that drives to a known state.

3. If this ÉlanSC310 microcontroller input is always driven to a known state, then no external termination is required.

4. If the pin is configured as an input, it should be terminated with a discrete pull-up or pull-down resistor, or it should always be

driven to a known state.
