Description
These bits are status flags that indicate error-free
transmission of the transmit message in the
corresponding mailboxes 1 to 15. When the
message in mailbox n (n = 1 to 15) has been
transmitted error-free, TXACKn is set to 1.
[Setting condition]
Completion of message transmission for
corresponding mailbox
