2.3.9 P120 to P127 (Port 12)
These are 8-bit input/output ports. Besides serving as input/output ports, they function as segment signal
output pins of LCD controller/driver.
The following operating modes can be specified bit-wise or byte-wise.
(1) Port mode
These ports function as 8-bit input/output ports. They can be specified bit-wise as input or output
ports with port mode register 12.
(2) Control mode
These ports function as segment output signal pins (S16 to S23) of LCD controller/driver.
2.3.10 P130 to P136 (Port 13)
These are 8-bit input/output ports. Besides serving as input/output ports, they function as segment signal
output pins of LCD controller/driver.
The following operating modes can be specified bit-wise or byte-wise.
(1) Port mode
These ports function as 8-bit input/output ports. They can be specified bit-wise as input or output
ports with port mode register 13. When used as input ports, pull-up resistors can be connected by
defining the pull-up resistor option register 7.
(2) Control mode
These ports function as segment output signal pins (S8 to S15) of LCD controller/driver.
2.3.11 P140 to P147 (Port 14)
These are 8-bit input/output ports. Besides serving as input/output ports, they function as segment signal
output pins of LCD controller/driver.
The following operating modes can be specified bit-wise or byte-wise.
(1) Port mode
These ports function as 8-bit input/output ports. They can be specified bit-wise as input or output
ports with port mode register 14.
(2) Control mode
These ports function as segment output signal pins (S0 to S7) of LCD controller/driver.
2.3.12 CTxD
These pin functions as CAN-controller transmit output.
2.3.13 CRxD
These pin functions as CAN-controller receive input.
