Doc ID 16912 Rev 5 535/936
BCC bit in the MCR is negated, then the whole Rx Individual Mask Registers address range
(0x0880–0x097F) is considered reserved space.
Note: The individual Rx Mask per Message Buffer feature may not be available in low cost MCUs.
Please consult the specific MCU documentation to find out if this feature is supported. If not
supported, the address range 0x0880–0x097F is considered reserved space, independent
of the value of the BCC bit.
