16.7.10 Receive Buffer 14 Mask Registers (RX14MSKHI, RX14MSKLO)
The receive buffer 14 mask registers have the same structure as the receive global mask registers and are
used to mask buffer 14.

Table 16-21. RX14MSKHI, RX14MSKLO Field Descriptions
The receive global mask registers use four bytes. The mask bits are applied to all
receive-identifiers, excluding receive-buffers 14 and 15, which have their own specific mask
registers.
Base ID mask bits MID[28:18] are used to mask standard or extended format frames.
Extended ID bits MID[17:0] are used to mask only extended format frames.
The RTR/SRR bit of a received frame is never compared to the corresponding bit in the
message buffer ID field. However, remote request frames (RTR = 1) once received, are never
stored into the message buffers. RTR mask bit locations in the mask registers (bits 11 and
31) are always zero, regardless of any write to these bits.
The IDE bit of a received frame is always compared to determine if the message contains a
standard or extended identifier. Its location in the mask registers (bit 12) is always one,
regardless of any write to this bit.
The receive buffer 14 mask registers use 4 bytes.
Base ID mask bits MID[28:18] are used to mask standard or extended format frames.
Extended ID bits MID[17:0] are used to mask only extended format frames.
