Cancellation Request
Each Tx Buffer has its own Cancellation Request bit. Writing a '1' will set the corresponding
Cancellation Request bit; writing a '0' has no impact. This enables the Host to set cancellation
0:31
requests for multiple Tx Buffers with one write to TXBCR. TXBCR bits are set only for those Tx
CR
Buffers configured via TXBC. The bits remain set until the corresponding bit of TXBRP is reset.

Transmission Occurred.
Each Tx Buffer has its own Transmission Occurred bit. The bits are set when the
corresponding TXBRP bit is cleared after a successful transmission. The bits are reset
when a new transmission is requested by writing a '1' to the corresponding bit of register
TXBAR.
