AT91SAM9261 Preliminary
Transmit Data Cancellation
Endpoints Without Dual-Banks
Endpoints With Dual-Banks
Some endpoints have dual-banks whereas some endpoints have only one bank. The procedure
to cancel transmission data held in these banks is described below.
To see the rganization of dual-bank availablity refer to
There are two possibilities: In one case, TXPKTRDY field in UDP_CSR has already been set. In
the other instance, TXPKTRDY is not set.
