Section 16 Controller Area Network (HCAN)
Bit 1—Halt Request (MCR1): Controls halting of the HCAN module.
Bit 1: MCR1

Bit 0—Reset Request (MCR0): Controls resetting of the HCAN module.
Bit 0: MCR0

In order for GSR3 to change from 1 to 0 after 0 is written to MCR0, time is required before the
HCAN is internally reset. There is consequently a delay before GSR3 is cleared to 0 after MCR0
is cleared to 0.
16.2.2
The general status register (GSR) is an 8-bit readable register that indicates the status of the CAN
bus.
Bits 7 to 4—Reserved: These bits always read 0.
