This input pin controls the chip power down. When this pin is active, the
clock supply to the chip will be inhibited and the output pins will be tri-
stated as defined in CR4 and CR6. The PDCIN is pulled down
internally. Its active state is defined by bit 4 of CRA (PDCHACT).
Default is high active.
PDCIN can be programmed by CR0D register as input pin IRRX2 for
serial infrared communication.
1.4 Multi-Mode Parallel Port
The following pins have eight functions, which are controlled by bits PRTMOD0, PRTMOD1, and
PRTMOD2 of CR0 and CR9 (refer to section 6.0, Extended Functions).

PRINTER MODE: BUSY
An active high input indicates that the printer is not ready to receive
data. This pin is pulled high internally. Refer to the description of the
parallel port for the definition of this pin in ECP and EPP mode.
EXTENSION FDD MODE: MOB2
This pin is for Extension FDD B; the function of this pin is the same as
that of the MOB pin.
EXTENSION ADAPTER MODE: XIRQ
This pin is an interrupt request generated by the Extension Adapter
and is an active high input.
EXTENSION 2FDD MODE: MOB2
This pin is for Extension FDD A and B; the function of this pin is the
same as that of the MOB pin.
JOYSTICK MODE: NC pin.
