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 to AD07
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 to AD15
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.
1P31
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 output
pin.
2P32
E
In single chip mode this is a general-purpose I/O port.
WRL
In external bus mode, this pin functions as the data bus lower 8-bit write
strobe signal output pin.
3P33
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.
4P34
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 input
pin.
5P35
E
In single chip mode this is a general-purpose I/O port.
HAK
In external bus mode, this pin functions as the hold acknowledge signal
output pin.
6P36
E
In single chip mode this is a general-purpose I/O port.
RDY
In external bus mode, this pin functions as the ready signal input pin.
