Reserved, should be cleared.
Current state of clear-to-send. Starting two serial clock periods after reset, CTS reflects the
state of UnCTS. If UnCTS is detected asserted at that time, COS is set, which initiates an
interrupt if UACRn[IEC] is enabled.
0 The current state of the UnCTS input is asserted.
1 The current state of the UnCTS input is deasserted.
