interrupt will be generated again after the last byte transfer, the TxRDY flag remains set. (Note
that the LUEE bit should be cleared to 0 because an underrun error occurs to terminate the
transfer if the LUEE bit in IECTR is set to 1.) Note, however, that the TxRDY interrupt should
be disabled because the TxRDY interrupt is always generated.

interrupt and clears the SRQ flag to 0.
