I/O PORTS (MCU MODULE)
The MCU Module has three ports: Port1, Port3,
and Port 4. (Refer to the PSD Module section on I/
O ports B, C and D).
Port1 - Port3 are the same as in the standard 8032
micro-controllers, with the exception of the addi-
tional special peripheral functions (see Table 28).
All ports are bi-directional. Pins of which the alter-
native function is not used may be used as normal
bi-directional I/O.
The use of Port1- Port4 pins as alternative func-
tions are carried out automatically by the
μPSD3251F device provided the associated SFR
Bit is set HIGH.
