4.4 General Purpose P-Port
4.4.1 Introduction
The P-Port is an 8-bit (P0/P7) general purpose parallel port in which each port pin can be
individually programmed as input (level or falling edge sensitive) or output.
1
The data direction and sensitivity for each bit are programmed through PCDR and PCSR 8-bit
registers.
Port inputs are sampled on each INCYCLE rising edge. Detection of a level change is
performed, provided the input remains at the same level for at least one INCYCLE cycle.
2
The Port input data is stored into the 8-bit Port Input Register (PIR). The Port output data is
stored into the 8-bit Port Output Register (POR).

D950-Core Parallel I/O Port
Notes 1:
PPort can be used as a branch condition.
PIR value is set to 1 on falling edge detection,until the port is tested.
The significant bit are 8-LSBs (8-MSBs=undefined when reading).
