D16 to D23
C
External data bus bits 16-23
Valid only in external bus 16-bit mode.
These pins can be used as ports in external bus 8-bit mode
External data bus bits 24-31
External address output bits 0-7
External address output bits 8-15
External address output bits 16-23
These pins can be used as ports according to setting
External data bus output bit 24
This pin can be used as a port according to setting
Power supply pin. Analog power supply for A/D converter
A/D converter reference voltage supply
Power supply pin. Analog power supply for A/D converter
A/D converter reference voltage supply. Analog input pin.
INT0-INT3: External interrupt input. When the corresponding external
interrupt is enabled, this input is in use at all times, so that output from
other functions must be stopped unless used intentionally
PJ0-PJ3: General purpose input/output port
TIN0-TIN2: Reload timer input. When the corresponding timer input is
enabled, this input is in use at all times, so that output from other
functions must be stopped unless used intentionally.
INT4-INT6: External interrupt input. When the corresponding external
interrupt is enabled, this input is in use at all times, so that output from
other functions must be stopped unless used intentionally.
PJ4-PJ6: General purpose input/output port
ATG: A/D converter external trigger input. When selected as an A/D start
source, this input is in use at all times, so that output from other functions
must be stopped unless used intentionally.
INT7: External interrupt input. When the corresponding external interrupt
is enabled, this input is in use at all times, so that output from other
functions must be stopped unless used intentionally.
PJ7: General purpose input/output port
SI0: UART0 data input. When the UART0 channel is in input operation,
this input is in use at all times, so that output from other functions must
be stopped unless used intentionally.
PI0: General purpose input/output port.
SO0: UART0 data output. This function is valid when the UART0 data
output function setting is disabled.
PI1: General purpose input/output port. This function is valid when the
UART0 data output function setting is disabled.
