The HCAN2 halt mode is provided to enable mailbox settings to be changed without performing
an HCAN2 hardware or software reset. In HCAN2 halt mode, the contents of all registers are
retained. Figure 15.14 shows a flowchart of HCAN2 halt mode.
HCAN2 halt mode is entered by setting the halt request bit (MCR1) to 1 in the master control
register (MCR). If the CAN bus is operating, the transition to HCAN2 halt mode is delayed until
the bus becomes idle.
HCAN2 halt mode is cleared by clearing MCR1 to 0.
