RESET:
The receive buffer 14 mask registers have the same structure as the receive global
mask registers and are used to mask buffer 14.
The receive buffer 15 mask registers have the same structure as the receive global
mask registers and are used to mask buffer 15.
This register reflects various error conditions, general status, and has the enable bits
for three of the TouCAN interrupt sources. The reported error conditions are those
which have occurred since the last time the register was read. A read clears these bits
to zero.

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 regis-
ters.
Base ID mask bits MID[28:18] are used to mask standard or extended format frames. Ex-
tended 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 mes-
sage 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 20 and
zero) 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 19) is always one, re-
gardless of any write to this bit.
