42.3.5 Rx Mailboxes Global Mask Register (CANx_RXMGMASK)
This register is located in RAM.
RXMGMASK is provided for legacy support.
When the MCR[IRMQ] bit is negated, RXMGMASK is always in effect.
When the MCR[IRMQ] bit is asserted, RXMGMASK has no effect.
RXMGMASK is used to mask the filter fields of all Rx MBs, excluding MBs 14-15,
which have individual mask registers.
This register can only be written in Freeze mode as it is blocked by hardware in other
modes.
