Notes:
All pull-up and pull-down resistor requirements are specified in ohms.
1.
A [–] implies that for this “programmable” pin function, no external termination is required.
2. 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.
3. When this pin’s function is a DMA request input, it should be terminated with a pull-down resistor if not connected to an ex-
ternal device that drives to a known state.
4. If this élanSC300 microcontroller input is driven directly with a logic gate, then no external termination is required at the
élanSC300 microcontroller pin. The termination on the PCMCIA socket signal is still required per the PCMCIA 2.1 specifica-
tion.
5. If this élanSC300 microcontroller input is always driven to a known state, then no external termination is required.
6. 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.
