Function
46
BGRNT/P81
F
External bus open reception output
This function is valid when external bus open reception output is
permitted. “L” is output if the external bus is opened. Can be used
as a port when the external bus open reception output is prohibit-
ed.
47
BRQ/P82
C
External bus open request input
This function is valid when external bus open request input is per-
mitted. “1” is input if the external bus requests to be opened.
Can be used as a port when the external bus open request input is
not used.
48
RD/P83
F
External bus read strobe output
This function is valid when external bus read strobe output is per-
mitted. Can be used as a port when the external bus read strobe
output is prohibited.
49
WR0/P84
F
External bus write strobe output
This function is valid in external bus mode. Can be used as a port
in single-chip mode.
50
WR1/P85
F
External bus write strobe output
This function is valid in external bus mode and with 16-bit buses.
Can be used as a port in single-chip mode or with external 8-bit
bus.
51
CLK/P86
F
System clock output
Outputs the same clock frequency as the external bus operation.
Can be used as a port when it is not otherwise used.
53
54
55
56
INT0/PC0
INT1/PC1
INT2/PC2
INT3/PC3
H
External interruption request inputs 0 to 3
These inputs are always used when dealing with external interrup-
tions is permitted, so output by ports should be stopped except
when carried out intentionally.
Can be used to reset standby as input is permitted in this port un-
der standby status.Can be used as ports when external interrup-
tion request input is not used.

60
AIN0/INT4/PC4
BIN0/INT5/PC5
AIN1/INT6/PC6
BIN1/INT7/PC7
H
External interruption request inputs 4 to 7
These inputs are always used when dealing with external interrup-
tions is permitted, so output by ports should be stopped except
when carried out intentionally. Can be used to reset standby as in-
put is permitted in these ports under standby status.
[ AIN, BIN ] Up/down timer input
This input is always used when input is permitted, so output by
ports should be stopped except when carried out intentionally.
Can be used as a port when external interruption request input and
up/down timer input are not used.
