The transmit wait register (TXPR) is a 16-bit readable/writable register that is used to set a
transmit wait after a transmit message is stored in a mailbox (buffer) (CAN bus arbitration wait).
Bits 15 to 9 and 7 to 0—Transmit Wait Register (TXPR7 to TXPR1, TXPR15 to TXPR8):
These bits set a transmit wait for the corresponding mailboxes.
Bit y: TXPRx

1
Bit 8—Reserved: This bit always reads 0. The write value should always be 0.
