COM2 serial data input from the communication link (modem
or peripheral device).
COM2 serial data output to the communication link (modem
or peripheral device).
Serial data-in from a external codec device
Serial data-out to a exteral codec device
Frame sync of SDI/SDO. This signal is an input signal during
"slave mode" or output signal during "master mode"
Serial Clock for SDI/SDO transfering. This signal is an input
signal during "slave mode" or output signal during "master
mode"
If MD[24] is pull down, this pin serves as an external interrupt
request. A active high-state in this pin will make EIER[12] be
set. In this mode, this pin can also serve as an interrupt
request pin for an IDE slot.
If MD[24] is pull high, this pin serves a "resume" request to
wake up the chip from "DOZE" mode.
If MD[24] is pull down, this pin serves as an external interrupt
request. A active high-state in this pin will make EIER[13] be
set. In this mode, this pin can also serve as an interrupt
request pin for an IDE slot.
If MD[24] is pull high, this pin serves a "resume" request to
wake up the chip from "SLEEP" mode.
