The ABACK1 and ABACK0 are 16-bit read/conditionally-write registers. These registers are used
to signal to the CPU that a mailbox transmission has been aborted as per its request. When an
abort has succeeded the RCAN-TL1 sets the corresponding bit in the ABACK register. The CPU
may clear the Abort Acknowledge bit by writing a ‘1’ to the corresponding bit location. Writing a
‘0’ has no effect. An ABACK bit position is set by the RCAN-TL1 to acknowledge that a TXPR
bit has been cleared by the corresponding TXCR bit.
• ABACK1
Note: * Only when writing a ‘1’ to clear.
Bits 15 to 0 — Notifies that the requested transmission cancellation of the corresponding Mailbox
has been performed successfully. The bit 15 to 0 corresponds to Mailbox-31 to 16 respectively.
• ABACK0
Note: * Only when writing a ‘1’ to clear.
Bits 15 to 1 — Notifies that the requested transmission cancellation of the corresponding Mailbox
has been performed successfully. The bit 15 to 1 corresponds to Mailbox-15 to 1 respectively.
