Register 29: EPI DMA Transmit Count (EPIDMATXCNT), offset 0x208
This register is used to program the total number of transfers (byte, halfword or word) by the µDMA
to WRFIFO. As each transfer is processed by the EPI, the TXCNT bit field value is decreased by 1.
When TXCNT = 0, the EPI's uDMA request signal is deasserted.

Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
