R5 Port
R5 is an 7-bit port (address 0CA_H). Each I/O pin can inde-
pendently used as an input or an output through the R5DD
register (address 0CB_H).
The control registers for R5 are shown below

R6 Port
R6 is an 1-bit CMOS bidirectional I/O port (address
0CC_H). Each I/O pin can independently used as an input or
an output through the R6DD register (address 0CD_H).
