Bits 31:0 – CRn[31:0] 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 requests for multiple Tx Buffers with one write to TXBCR. TXBCR bits are set only for those Tx Buffers configured via TXBC. The bits remain set until the corresponding bit of TXBRP is reset.

Value	Description
0	No cancellation pending.
1	Cancellation pending.
