13.8.15.2 Global Interrupt Mask Register (CANGIM)
The set up for the interrupt mask register is the same as for the interrupt flag register. If a bit is set, the
corresponding interrupt is enabled. This register is EALLOW protected.
The GMIF has no corresponding bit in the CANGIM because the mailboxes have individual mask bits in
the CANMIM register.
