9.3.9 Port Registers
There are two sets of registers per I/O port: the Port Configuration Registers (PCR) which
consist of four 8-bit registers; and the Port Data Registers (PDR) which include three 8-bit
registers. The PCR is used for setting up the port configuration, while the PDR enables the
microcontroller to write or read port data or status bits. Tables 13 and 14 show the names
and the registers and the ports to which they belong.
All the registers in the PCR and PDR are 8-bits wide and each bit is associated with a
pin in the I/O port. In Table 15, the LSB of the Data In Register of Port A is connected to
pin PA0, and the MSB is connected to PA7. This pin configuration also applies to other
registers and ports. For example, in the Direction Register of Port A, writing a hex value of
07 to the register configures pins PA0 – PA2 as output pins, while PA3 – PA7 remain as
input pins.
Registers can be accessed by the microcontroller during normal read/write bus cycles.
The I/O address offset of the registers are listed in the System Configuration section.
