Hardware standby input pin
95 to 102
P00 to P07
D
In single chip mode, these are general purpose I/O pins. When set for
input, they can be set by the pull-up resistance setting register
(RDR0). When set for output, this setting will be invalid.
AD00 toAD07
In external bus mode, these pins function as address low output/data
low I/O pins.
103 to 110
P10 to P17
D
In single chip mode, these are general purpose I/O pins. When set for
input, they can be set by the pull-up resistance setting register
(RDR1). When set for output, the setting will be invalid.
AD08 toAD15
In external bus mode, these pins function as address middle output/
data high I/O pins.
111 to 118
P20 to P27
E
In single chip mode this is a general-purpose I/O port.
A16 to A23
In external bus mode, these pins function as address high output
pins.
120
P30
E
In single chip mode this is a general-purpose I/O port.
ALE
In external bus mode, this pin functions as the address latch enable
signal output pin.
1
P31
E
In single chip mode this is a general-purpose I/O port.
RD
In external bus mode, this pin functions as the read strobe signal out-
put pin.
2

write strobe signal output pin.
3
P33
E
In single chip mode this is a general-purpose I/O port.
WRH
In external bus mode, this pin functions as the data bus upper 8-bit
write strobe signal output pin.
4
P34
E
In single chip mode this is a general-purpose I/O port.
HRQ
In external bus mode, this pin functions as the hold request signal in-
put pin.
5
P35
