9.2 I/O Ports Configuration
R0 Ports
R0 is an 8-bit CMOS bidirectional I/O port (address
0C0
H
). Each I/O pin can independently used as an input or
an output through the R0DD register (address 0C1
H
).
The control registers for R0 are shown below.
In addition, Port R0 is only digital I/O. After reset, R0DD
value is "0", R0 acts as normal digital input port.
R1 Ports
R1 is an 8-bit CMOS bidirectional I/O port (address
0C2
H
). Each I/O pin can independently used as an input or
an output through the R1DD register (address 0C3
H
).
R1 port have secondary functions as following table.
The control registers for R1 are shown below.
Port R1 is multiplexed with various special features.The
control registers controls the selection of alternate func-
tion. After reset, R1 port acts as normal digital input port.
The way to select alternate function such as A/D input or
HD,VD will be shown in each peripheral section.
