Section 19 Controller Area Network (RCAN-ET)
19.5.3
The TXACK0 is a 16-bit read/conditionally-write registers. This register is used to signal to the
CPU that a mailbox transmission has been successfully made. When a transmission has succeeded
the RCAN-ET sets the corresponding bit in the TXACK register. The CPU may clear a TXACK
bit by writing a '1' to the corresponding bit location. Writing a '0' has no effect.
• TXACK0
Note: * Only when writing a '1' to clear.
Bit 15 to 1 — Notifies that the requested transmission of the corresponding Mailbox has been
finished successfully. The bit 15 to 1 corresponds to Mailbox-15 to 1 respectively.
Bit 0 — This bit is always '0' as this is a receive-only mailbox. Writing a '1' to this bit position has
no effect and always read back as a '0'.
