UART Modules
24.3.12 UART Input Port Register (UIPn)
The UIPn registers, shown in
24.3.13 UART Output Port Command Registers (UOP1n/UOP0n)
The UnRTS output can be asserted by writing a 1 to UOP1n[RTS] and negated by writing a 1 to
UOP0n[RTS]. See

The minimum value that can be loaded on the concatenation of
UBG1n with UBG2n is 0x0002. The UBG2n reset value of 0x00 is
invalid and must be written to before the UART transmitter or receiver
are enabled. Both UBG1n and UBG2n are write-only and cannot be
read by the CPU.

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[RTS].
0 The current state of the UnCTS input is logic 0.
1 The current state of the UnCTS input is logic 1.
