Section 16 Controller Area Network (HCAN)
16.2.6
The transmit wait cancel register (TXCR) is a 16-bit readable/writable register that controls
cancellation of transmit wait messages in mailboxes (buffers).
Bits 15 to 9 and 7 to 0—Transmit Wait Cancel Register (TXCR7 to TXCR1, TXCR15 to
TXCR8): These bits control cancellation of transmit wait messages in the corresponding HCAN
mailboxes.
Bit y: TXCRx
0
1
Bit 8—Reserved: This bit always reads 0. The write value should always be 0.
