Bits 31:0 – CFn[31:0] Cancellation Finished

Each Tx Buffer has its own Cancellation Finished bit.

The bits are set when the corresponding TXBRP bit is cleared after a cancellation was requested via TXBCR. In case the corresponding TXBRP bit was not set at the point of cancellation, CF is set immediately.

The bits are reset when a new transmission is requested by writing ‘1’ to the corresponding bit of register TXBAR.
