31.3.13 UART Output Port Command Registers (UOP1n/UOP0n)
The U
n
RTS output can be asserted by writing a 1 to UOP1
n
[RTS] and negated by writing a 1 to
UOP0
n
[RTS].

Functional Description
This section describes operation of the clock source generator, transmitter, and receiver.
31.4.1
Transmitter/Receiver Clock Source
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.

CTS
Current state of clear-to-send. The UnCTS 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 UnCTS input is logic 0.
1 The current state of the UnCTS input is logic 1.
