Parallel Port Data Register A[3:1] = 100, Bit[15:12]Read only, Bit[11:8] Read/Write:
PIN[3:0]: is the read data from parallel input port [3:0] pins, the parallel input are sampled every 16
cycles of the system clock. The read bit is high when the input pin is low.
PO[3:0]: is the data output to the PO[3:0] pins, write 1 in the register will output high on the related PO
pin.
Parallel Port Control Register A[3:1] = 100, Read/Write:
PIEN[3:0] (Parallel input enable): The bit = 1 is used to enable the related parallel input pin of PI[3:0].
POEN[3:0] (Parallel output enable): The bit = 1 is used to enable the related parallel output pin of
PO[3:0].
READY Control Register A[3:1] = 101, Read/Write:
This register is effective only when Host interface access type 2 is selected. The access cycle is 2-
cycle when Fast bit is set high, otherwise the access cycle is 3-cycle.
