Section 15 Controller Area Network for Tiny (TinyCAN)
15.3.8
TXCR cancels transmission of transmit pending messages in Mailboxes. By setting the TXCR bit
correspondent to TXPR, TXPR is cleared to 0. If the transmission has been canceled successfully,
the corresponding bits in both TXPR and TXCR are cleared to 0 and then the corresponding bit in
ABACK is set. Writing 0 to the bit in TXCR is ignored.
15.3.9
TXACK is a status flag that indicates the successful transmit completion of Mailbox transmit
messages.

Description
Reserved
These bits are always read as 0.
[Setting condition]
The corresponding bit of a mailbox is set to 1
[Clearing condition]
When the corresponding bit in TXPR is cleared (the
transmit message is canceled successfully)
Note: Writing 1 to these bits is enabled only when the
Reserved
This bit is always read as 0. This bit is relevant to the
receive-only Mailbox, and its value cannot be changed.
Description
Reserved
These bits are always read as 0.
[Setting condition]
When transmission of the message in the corresponding
Mailbox has completed successfully
[Clearing condition]
When 1 is written to these bits
TXPR bit corresponding to Mailbox is set to 1.
