| 23:16 | RXIDMASK | R/W | 0h | Receive ID mask. This field is effective in LIN mode only.This 8-bit mask is used for filtering an incoming ID message and compare it to the ID-byte. A compare match of the received ID witht the RX ID mask will set the ID RX flag and trigger and ID interrupt if enabled. A 0 bit in the mask indicates that bit is compared to the ID-byte. A 1 bit in the mask indicates that that bit is filtered and therefore not used in the compare. When HGENCTRL is set to 1, this field must be set to 0xFF. |
| 15:8 | RESERVED_1 | R | 0h | Reserved |
| 7:0 | TXIDMASK | R/W | 0h | Transmit ID mask. This field is effective in LIN mode only. This 8-bit mask is used for filtering an incoming ID message and compare 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. 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 not used for the compare. When HGENCTRL is set to 1, this field must be set to 0xFF. |
