9.3 RC and RCIO registers
RC is a 2-bit bidirectional I/O port (address C4
H
). Each
pin can be set individually as input and output through the
RCIO register (address C5
H
).

9.4 RD and RDIO registers
RD is a 4-bit bidirectional I/O port (address C6
H
). Each
pin can be set individually as input and output through the
RDIO register (address C7
H
).
