This implements SPIM TX workaround suggested from section 3.8.1 from Anomaly 109 addendum. In workaround case we first keep track of original maxcnt values, then initiate "fake" transfer with zero-length maxcnt values. Once the "fake" transfer is triggered, we handle it, fill in the original maxcnt values and restart the transmission.
