M_CAN_TXBCF field descriptions (continued)
Field Description
Each Tx Buffer has its own Cancellation Finished bit. The bits are set when the corresponding TXBRP bit
is cleared after a cancellation was requested via TXBCR. In case the corresponding TXBRP bit was not
set at the point of cancellation, CF is set immediately. The bits are reset when a new transmission is
requested by writing 1 to the corresponding bit of register TXBAR.
0 No transmit buffer cancellation
1 Transmit buffer cancellation finished
