3.2.6 P80 to P87 (Port 8)
These are 8-bit I/O ports. Besides serving as I/O ports, they function as segment signal output of LCD controller/
driver.
The following operating modes can be specified in 1-bit units.
(1) Port mode
These ports function as 8-bit I/O ports. They can be specified as input or output ports in 1-bit units with port
mode register 8 (PM8). When they are used as input ports, internal pull-up resistors can be used by defining
pull-up resistor option register H (PUOH).
(2) Control mode
These ports function as segment signal output pins (S32 to S39) of LCD controller/driver.
3.2.7 P90 to P97 (Port 9)
These are 8-bit I/O ports. Besides serving as I/O ports, they function as segment signal output of LCD controller/
driver.
The following operating modes can be specified in 1-bit units.
(1) Port mode
These ports function as 8-bit I/O ports. They can be specified as input or output ports in 1-bit units with port
mode register 9 (PM9). When they are used as input ports, internal pull-up resistors can be used by defining
pull-up resistor option register H (PUOH).
(2) Control mode
These ports function as segment signal output pins (S24 to S31) of LCD controller/driver.
3.2.8 P100 to P103 (Port 10)
These are 4-bit I/O ports. They can be specified as input or output ports in 1-bit units with port mode register 10
(PM10). When they are used as input ports, internal pull-up resistors can be used by defining pull-up resistor option
register H (PUOH).
LED can be driven directly.
