Name and Functions
Port A: This is a 4-bit I/O port. Input or
output can be designated for each bit by
means of port control register A (PCRA).
Port 1: This is an 8-bit I/O port. Input or
output can be designated for each bit by
means of port control register 1 (PCR1).
Port 3: This is an 8-bit I/O port. Input or
output can be designated for each bit by
means of port control register 3 (PCR3).
Port 5: This is an 8-bit I/O port. Input or
output can be designated for each bit by
means of port control register 5 (PCR5).
Port 6: This is an 8-bit I/O port. Input or
output can be designated for each bit by
means of port control register 6 (PCR6).
Port 7: This is an 8-bit I/O port. Input or
output can be designated for each bit by
means of port control register 7 (PCR7).
Port 8: This is an 8-bit I/O port. Input or
output can be designated for each bit by
means of port control register 8 (PCR8).
Port 9: This is a 4-bit I/O port. Input or
output can be designated for each bit by
means of port control register 9 (PCR9).
Port 4 (bit 3): This is an internal 1-bit input
port.
Port 2: This is an internal 5-bit I/O port.
Input or output can be designated for each
bit by means of port control register 2
(PCR2).
