15.2.8
The abort acknowledge register (ABACK) is a 16-bit readable/writable register containing status
flags that indicate normal cancellation (aborting) of a mailbox (buffer) transmit messages.
Note: * Only a write of 1 is permitted, to clear the flag.
Bits 15 to 9 and 7 to 0—Abort Acknowledge Register: These bits indicate that a transmit
message in the corresponding mailbox has been canceled (aborted) normally.
Bit 8—Reserved: This bit always reads 0. The write value should always be 0.
