This is a general-purpose I/O port.
These are event input pins for 16-bit re-load timers 0 and 1.
Since this input is used as required for 16-bit re-load timers 0 and
1 operation, output by other functions must be suspended except
for intentional operation.
These are event output pins for output compare 1 (OCU) ch.4 and
ch.6.
This function is valid when output for each channel is enabled.
This is a general-purpose I/O port.
This function is valid when TO0 and TO1 output are disabled.

These are output pins for 16-bit re-load timers 0 and 1.
This function is valid when TO0 and TO1 output are enabled.
These are event output pins for output compare 1 (OCU) ch.5 and
ch.7.
This function is valid when output for each channel is enabled.
This is a general-purpose I/O port.
This function is valid with port output specified for the LCD
controller/driver control register.
These are common pins for the LCD controller/driver.
This function is valid with common output specified for the LCD
controller/driver control register.
This is a general-purpose I/O port.
This function is valid with port output specified for the LCD
controller/driver control register.
These are segment outputs for the LCD controller/driver.
This function is valid with segment output specified for the LCD
controller/driver control register.
This is a general-purpose I/O port.
The maximum I
OL
can be 10mA.
This function is valid with port output specified for the LCD
controller/driver control register.
These are segment outputs for the LCD controller/driver.
This function is valid with port output specified for the LCD
controller/driver control register.
These are pins dedicated to LCD segments 00 to 07 for the LCD
controller/driver.
This is a general-purpose I/O port.
This function is valid with port output specified for the LCD
controller/driver control register.
These are pins for LCD segments 08 to 15 for the LCD controller/
driver.
Units of four ports or segments can be selected by the internal
register in the LCD controller.
