Description
HRxD Interrupt Enable
Selects whether an IRQ2 interrupt is caused by PF0 or
HRxD pin.
0: An IRQ2 interrupt is caused by pin PF0
1: An IRQ2 interrupt is caused by the HRxD pin
HTxD Transmission Stop
Controls transmission stop of the HTxD pin.
0: Enables transmission from the HTxD pin
1: Fixes an output level of the HTxD pin at 1 and
HCAN Enable
Selects PK7/HRxD1 and PK6/HTxD1 pin function
0: puts PK7 and PK6 pins in port function
1: puts PK7 pin in HRxD1 function and puts PK6 pin in
Reserved
