C
These pins use bits 16 to 23 of the external data bus.
They can be used as a port (P20 to P27) if the external bus
width is 8 bits.

I/O
C
This is for external ready input. “0” is input if the bus cycle be-
ing executed is incomplete. It can be used as a port when not
otherwise used.

BGRNT/P81
I/O
H
This is the external bus open reception output. “L” is output if
the external bus is opened. It can be used as a port when not
otherwise used.
