UART Modules
23.3.13 UART Output Port Command Registers (UOP1n/UOP0n)
The URTSn output can be asserted by writing a 1 to UOP1n[RTS] and negated by writing a 1 to
UOP0n[RTS].
23.4
This section describes operation of the clock source generator, transmitter, and receiver.
23.4.1
The internal bus clock serves as the basic timing reference for the clock source generator logic, which
consists of a clock generator and a programmable 16-bit divider dedicated to each UART. The 16-bit
divider is used to produce standard UART baud rates.

Current state of clear-to-send. The UCTSn value is latched and reflects the state of the input pin when UIPn is read.
Note: This bit has the same function and value as UIPCRn[CTS].
0 The current state of the UCTSn input is logic 0.
1 The current state of the UCTSn input is logic 1.
Reserved, must be cleared.
Output port output. Controls assertion (UOP1)/negation (UOP0) of URTSn output.
0 Not affected.
1 Asserts URTSn in UOP1. Negates URTSn in UOP0.
