R2 Port
R2 is an 8-bit CMOS bidirectional I/O port (address
0C4
H
). Each I/O pin can independently used as an input or
an output through the R2DD register (address 00C5
H
).
The control registers for R2 are shown below.
R4 Port
R4 is consrutced with 4-bit Open drain Output port and 4-
bit CMOS bidirectional I/O port (address 0C8
H
). Each I/O
pin can independently used as an input or an output
through the R4DD register (address 0C9
H
).
The control registers for R4 are shown below.
