85 to 92 83 to 90
P00 to P07
C
(CMOS)
This is a general purpose I/O port. A setting in the port 0 input
resistance register (RDR0) can be used to apply pull-up resistance
(RD00-RD07
= “1”) . (Disabled when pin is set for output.)
AD00 to
AD07
In multiplex mode, these pins function as the external address/data
bus low I/O pins.
D00 to D07
In non-multiplex mode, these pins function as the external data bus
low output pins.
93 to
100
91 to 98
P10 to P17
C
(CMOS)
This is a general purpose I/O port. A setting in the port 1 input
resistance register (RDR1) can be used to apply pull-up resistance
(RD10-RD17
= “1”) . (Disabled when pin is set for output.)
AD08 to
AD15
In multiplex mode, these pins function as the external address/data
bus high I/O pins.
D08 to D15
In non-multiplex mode, these pins function as the external data bus
high output pins.
1 to 4
99,100,
1, 2
P20 to P23
E
(CMOS/H)
This is a general purpose I/O port. When the bits of external address
output control register (HACR) are set to "1" in external bus mode,
these pins function as general purpose I/O ports.
A16 to A19
When the bits of external address output control register (HACR) are
set to "0" in multiplex mode, these pins function as address high
output pins (A16 to A19).
When the bits of external address output control register (HACR) are
set to "0" in non-multiplex mode, these pins function as address high
output pins (A16 to A19).
5 to 8
3 to 6
P24 to P27
E
(CMOS/H)
This is a general purpose I/O port. When the bits of external address
output control register (HACR) are set to "1" in external bus mode,
these pins function as general purpose I/O ports.
A20 to A23
When the bits of external address output control register (HACR) are
set to "0" in multiplex mode, these pins function as address high
output pins (A20 to A23).
When the bits of external address output control register (HACR) are
set to "0" in non-multiplex mode, these pins function as address high
output pins (A20 to A23).
PPG0 to
PPG3
Output pins for PPG.
97
P30
E
(CMOS/H)
This is a general purpose I/O port.
A00
In non-multiplex mode, this pin functions as an external address pin.
AIN0
8/16-bit up/down timer input pin (ch.0) .
