0 CTS Clear to send. This bit is the complement of
the UART clear to send, nUARTCTS,
modem status input. That is, the bit is 1
when nUARTCTS is LOW.

15:0 IBRD The integer baud rate divisor. RW 0x0
FBRD Register
Synopsis
The UART_FBRD Register is the fractional part of the baud rate divisor value.
The baud rate divisor is calculated as follows:
Baud rate divisor BAUDDIV = (FUARTCLK/(16 Baud rate))
where FUARTCLK is the UART reference clock frequency. The BAUDDIV is
comprised of the integer value IBRD and the fractional value FBRD. NOTE:
The contents of the IBRD and FBRD registers are not updated until
transmission or reception of the current character is complete.
