Notes:
All pull-up and pull-down resistor requirements are specified in ohms.
1. A [鈥揮 implies that for this 鈥減rogrammable鈥?pin function, no external termination is required.
2. This pin is an 鈥渁lternate pin function select input鈥?that is sampled at reset. This pin functions as a normal serial port output
after RESIN and IORESET are deasserted.
3. When this pin鈥檚 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 脡lanSC300 microcontroller input is driven directly with a logic gate, then no external termination is required at the
脡lanSC300 microcontroller pin. The termination on the PCMCIA socket signal is still required per the PCMCIA 2.1 specifica-
tion.
5. If this 脡lanSC300 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.
