I/O PORTS
The Z8Plus dedicates 14 lines to input and output. These lines
are grouped into two ports known as Port A and Port B. Port
A is an 8-bit port, bit programmable as either inputs or outputs.
Port B can be programmed to provide either standard in-
put/output, or the following special functions:
comparator input,
Directional Control and Special Function
Registers
Each port on the Z8Plus features a dedicated directional con-
trol register that determines (on a bit-wise basis) if a given
port bit operates as input or output.
Each port on the Z8Plus features a special function register
(
ister, implements (on a bit-by-bit basis) any special func-
tionality that can be defined for each particular port bit.

output,
All pins except
addition, the outputs of Port A on a bit-wise basis can be
configured for open-drain operation.The ports operate on
a bit-wise basis. As such, the register values for/at a given
bit position only affect the bit in question.
Each port is defined by a set of four control registers (Figure 26).
Input and Output Value Registers
Each port features an Output Value Register and an input
value register. For port bits configured as an input by means
of the directional control register, the input value register
