FILTER HIGH REGISTERS (FHRx)
Read/Write
Reset Value: Undefined
FIL[11:3] are the most significant 8 bits of a 12-bit
message filter. The acceptance filter is compared
bit by bit with the identifier and the RTR bit of the
incoming message. If there is a match for the set
of bits specified by the acceptance mask then the
message is stored in a receive buffer.
FILTER LOW REGISTERS (FLRx)
Read/Write
Reset Value: Undefined
FIL[3:0] are the least significant 4 bits of a 12-bit
message filter.

MASK HIGH REGISTERS (MHRx)
Read/Write
Reset Value: Undefined
MSK[11:3] are the most significant 8 bits of a 12-
bit message mask. The acceptance mask defines
which bits of the acceptance filter should match
the identifier and the RTR bit of the incoming mes-
sage.
