UART Transmit Byte Count Register
Indicates the number of bytes to transmit. This register is relevant only if DMA_MODE=1.
On transmit a command will complete (TX_DONE) when BYTE_COUNT=0. No more bytes will be sent until BYTE_COUNT is
modified again. Any EOP signalling from the DMA adapter will be ignored.
31:0 BYTE_COUNT[31:0] Number of bytes left to transmit
0xFFFFFFFF indicates infinite (counter will not decrement)
