*1: Circuits corresponding these signals are essential and therefore cannot be unused.
*2: If the ports corresponding to these signals in SCE8720C are set to output, pull-up
resistance is not necessary. If the ports are set to input, pull-up resistance is
necessary.
*3: When set to NC, the ROM in the card (SCE8720C) is selected.
*4: Keep all the RESERVED pins unconnected.
*5: Signals of POFF, PWSW#, PME0# (Wake On LAN), PME1# (Wake On Ring) operates
with V
controlling ON/OFF of the power supply. It is recommended that signal
CCSTB
inputs of PWSW#, PME0# and PME1# are set to low or high impedance for
compatibility with other cards (so that other cards can also use the same main circuit).
*6: For RS232C driver receiver on the evaluation board to be connected to the COM1 and
COM2 interfaces, use one that operates at 5V, or that operates at 3.3V and is 5V-
tolerant.
