Register Descriptions
14.3.8 UART Input Port Change Registers (UIPCRn)
The input port change registers (UIPCRn), Figure 14-9, hold the current state and the
change-of-state for CTS.
Table 14-7 describes UIPCRn fields.
14.3.9 UART Auxiliary Control Register (UACRn)
The UART auxiliary control registers (UACRn), Figure 14-7, control the input enable.

Current state. Starting two serial clock periods after reset, CTS reflects the state of CTS. If CTS is
detected asserted at that time, COS is set, which initiates an interrupt if UACRn[IEC] is enabled.
0 The current state of the CTS input is asserted.
1 The current state of the CTS input is negated.
