Serial data-in from a external codec device
Serial data-out to a external codec device
Frame sync of SDI/SDO. This signal is an input signal during
"slave mode" (CFGH[2] set low)or output signal during
"master mode" (CFGH[2] set high)
Serial Clock for SDI/SDO transferring. This signal is an input
signal if MD[25] is pulled low, and act as output signal during
is MD[25] is pull high.
This pin serves as an external interrupt request. A active
high-state in this pin will make EIER[12] be set. This pin may
also serve as an interrupt request pin for an IDE slot.
This pin serves as an external interrupt request. A active
