Circuit
type
Function
External data bus bits 16 to 23
C Only valid for external bus 16-bit mode. Can be used as ports in
single-chip and external bus 8-bit modes.
C
External data bus bits 24 to 31
Can be used as ports in single-chip mode.
External address bus bits 0 to 15
F Valid for external bus mode. Can be used as ports in single-chip
mode.
External address bus bits 16 to 23
[ INT16 to 23 ] are external interruption request inputs 16 to 23.
These inputs are always used when dealing with external interrup-
O tions is permitted, so output by ports should be stopped except
when carried out intentionally.
Can be used as ports when address bus and external interruption
request input are not used.
External RDY input
C
This function is valid when external RDY input is permitted. “0” is
input if the bus cycle being executed is not completed.
Can be used as a port when the external RDY input is not used.
