This anomaly applies to IC Rev. Engineering C, build codes CKAA-CA0, QIAA-CA0.
The RXPTRUPD event is generated when the STOP task is triggered, even though reception (RX) is disabled. Similarly, the TXPTRUPD event is generated when the STOP task is triggered, even though transmission (TX) is disabled.
A previous transfer has been performed with RX/TX enabled, respectively.
The indication that RXTXD.MAXCNT words were received/transmitted is false.
Ignore the RXPTRUPD and TXPTRUPD events after triggering the STOP task. Clear these events before starting the next transfer.
