(CMOS)
Simple serial I/O output pin
General-purpose input/output port
G
Functions as an external address pin in the non-multi-bus mode.
(CMOS/H)
Simple serial I/O clock input/output pin
General-purpose input/output port
F
Functions as an external address pin in the non-multi-bus mode.
(CMOS)
µPG output pin
General-purpose input/output port
G
Functions as an external address pin in the non-multi-bus mode.
(CMOS/H)
µPG input pin
General-purpose input/output port
F
Functions as an external address pin in the non-multi-bus mode.
(CMOS)
Functions as the output pin for output compare events.
General-purpose input/output port. It functions as the ALE pin in the
external bus mode.
D
(CMOS)
Functions as the address read permission signal (ALE) pin in the
external bus mode.
General-purpose input/output port. It functions as the RD pin in the
external bus mode.
D
(CMOS)
Functions as the read strobe output (RD) pin in the external bus
mode.
General-purpose input/output port. It functions as the WRL pin in the
external bus mode if the WRE bit of the EPCR register is set to "1".
D
In the external bus mode, functions as the write strobe output (WRL)
(CMOS)
pin of data on the lower side. This pin functions as a general-purpose
input/output port if the WRE bit of the EPCR register is set to "0".
General-purpose input/output port. It functions as the WRH pin in the
external bus mode of a 16-bit bus width if the WRE bit of the EPCR
register is set to "1".
D
Functions as the write strobe output (WRH) pin of data from the upper
(CMOS)
side in the external bus mode of a 16-bit bus width, and functions as a
general-purpose input/output port if the WRE bit of the EPCR register
is set to "0".
General-purpose input/output port. It functions as the HRQ pin in the
external bus mode if the HDE bit of the EPCR register is set to "1".
D
Functions as the hold request input (HRQ) pin in the external bus
(CMOS)
mode, and functions as a general-purpose input/output port if the
HDE bit of the EPCR register is set to "0".
