UART_RX_BYTE_COUNT

10.20.8 UART_RX_BYTE_COUNT
UART Receive Byte Count Register
Indicates the number of bytes to receive. This register is relevant only if DMA_MODE=1.
No end-of-packet (EOP) will be sent to the DMA adapter. If receive flow control is enabled it will be set to off. If flow control is
not enabled and data is received and the socket remains active, it will be forwarded to the adapter regardless of
BYTE_COUNT. BYTE_COUNT will stay 0 in this case (not decrement).
31:0 BYTE_COUNT[31:0] Number of bytes left to receive
0xFFFFFFFF indicates infinite (counter will not decrement)
