Description
General purpose input/output port.
G
In non-multibus bus mode, this pin functions as an external
(CMOS/H) address pin.
Single serial I/O clock input/output pin
General purpose input/output ports.
F
In non-multibus bus mode, this pin functions as an external
(CMOS) address pin.
µPG input pins
General purpose input/output ports.
G
In non-multibus bus mode, this pin functions as an external
(CMOS/H) address pin.
µPG input pin
General purpose input/output ports.
F

Output compare event output pins
D
(CMOS)
General purpose input/output port. In external bus mode, this
pin functions as the ALE pin
In external bus mode, this pin functions as the address load
enable signal (ALE) pin
D
(CMOS)
General purpose input/output port. In external bus mode, this
pin functions as the RD pin.
In external bus mode, this pin functions as the read strobe
output (RD) pin.
D
(CMOS)
General purpose input/output port. In external bus mode, this
pin functions as the WRL pin when the WRE bit in the EPCR
register is set to “1”.
In external bus mode, this pin functions as the lower data write
strobe output (WRL) pin. When the WRE bit in the EPCR
register is set to “0”,this pin functions as a general purpose
input/output port.
D
(CMOS)
General purpose input/output port. In external bus mode with
16-bit bus width, this pin functions as the WRH pin when the
WRE bit in the EPCR register is set to “1”.
In external bus mode with 16-bit bus width, this pin functions
as the higher data write strobe output (WRH) pin. When the
WRE bit in the EPCR register is set to “0”,this pin functions as
a general purpose input/output port.
