General Description
1.4.18 Port H I/O Pins (PTH1/KBD4–PTH0/KBD3)
Port H is a 2-bit special-function port that shares all of its pins with the
Keyboard Module (KBD). See Keyboard Module (KBD) on page 373
and I/O Ports on page 293.
1.4.19 CAN Transmit Pin (TxCAN)
TxCAN is the digital output from the MSCAN08 module. See MSCAN08
Controller (MSCAN08) on page 321.
1.4.20 CAN Receive Pin (RxCAN)
RxCAN is the digital input to the MSCAN08 module. See MSCAN08
Controller (MSCAN08) on page 321.
