CAN 0 Transmit Message Acknowledgement Register 0. This register
indicates which of CAN 0 message centers 1-8 have successfully transmitted
a message since the last read of this register. A logic one in a location
indicates a message has been transmitted from that message center. This
register is automatically cleared to 00h when read. This register should
always be read in conjunction with the C0TMA1 register to ascertain the
status of all message centers.
