Table 29-43. LIN Mask Register (LINMASK) Field Descriptions
Bit Field Value Description
31-24 Reserved 0 Reads return 0. Writes have no effect.
23-16 RX ID MASK 0-FFh Receive ID mask. These bits are effective in LIN mode only. This 8-bit mask is used for filtering an
incoming ID message and comparing it to the ID-byte. A compare match of the received ID with
the RX ID MASK will set the ID RX flag and trigger an ID interrupt if enabled (SET ID INT in
SCISETINT). A 0 bit in the mask indicates that bit is compared to the ID-byte. A 1 bit in the mask
indicates that bit is filtered and therefore is not used in the compare.
15-8 Reserved 0 Reads return 0. Writes have no effect.
7-0 TX ID MASK 0-FFh Transmit ID mask. These bits are effective in LIN mode only. This 8-bit mask is used for filtering
an incoming ID message and comparing it to the ID-byte. A compare match of the received ID with
the TX ID MASK will set the ID TX flag and trigger an ID interrupt if enabled (SET ID INT in
SCISETINT). A 0 bit in the mask indicates that bit is compared to the ID-byte. A 1 bit in the mask
indicates that bit is filtered and therefore is not used for the compare.
