PR_DIV1~0
PR_DIV1~0 - Pre-Divisor 1~0.
These bits select pre-divisor for external input clock 24M Hz. The clock through the pre-
divisor then inputs to baud rate divisor of UART.
RX_FSZ1~0 - Receiver FIFO Size 1~0
These bits setup receiver FIFO size when FIFO is enabled.
TX_FSZ1~0 - Transmitter FIFO Size 1~0
These bits setup transmitter FIFO size when FIFO is enabled.
