Function
E General-purpose I/O port.
(CMOS/H) This function is activated when the clock output specification
of the UART is “disabled”.
UART clock I/O pin.
This function is activated when the clock output specification
of the UART is “enabled”.
Input is used only as necessary while serving as UART input.
It is therefore necessary to stop output beforehand using other
functions unless intentionally used otherwise.
E General-purpose I/O port.
(CMOS/H) This function is activated when the output specification of the
PWM is “disabled”.
PWM timer output pin.
This function is activated when the waveform output specifica-
tion of the PWM timer is “enabled”.
D General-purpose I/O ports.
(CMOS/H) This function is always active.
External interrupt request input pins.
Input is used only as necessary while external interrupts are
enabled.
D General-purpose input port.
(CMOS/H) This function is always active.
External interrupt request input pin.
Input is used only as necessary while external interrupts are
enabled.
Timer clear trigger input pin for multi-function timer.
Input is used only as necessary while multi-function timer
input is enabled.
D General-purpose input port.
(CMOS/H) This function is always active.
External interrupt request input pin.
Input is used only as necessary while external interrupts are
enabled.
Trigger input pin for the A/D converter.
Input is used only as necessary while the A/D converter is
performing input.
C
(AD)
Open-drain type I/O ports.
This function is enabled when the analog input enable register
specification is “port”.
Analog input pins for the A/D converter.
This function is enabled when the analog input enable register
specification is “AD”.
