16.3.6
The HCAN halt mode is provided to enable mailbox settings to be changed without performing an
HCAN hardware or software reset. Figure 16-12 shows a flowchart of the HCAN halt mode.
HCAN halt mode is entered by setting the halt request bit (MCR1) to 1 in the master control
register (MCR). However, if the CAN bus is operating at the time of a transition, the transition to
HCAN ALT mode is delayed until the bus becomes idle.
HCAN halt mode is cleared by clearing MCR1 to 0.
16.3.7
There are 12 HCAN interrupt sources, to which five independent interrupt vectors are assigned.
Table 16-5 lists the HCAN interrupt sources.
With the exception of the reset processing vector (IRR0), these sources can be masked. Masking is
implemented using the mailbox interrupt mask register (MBIMR) and interrupt mask register
(IMR).
