UART Modules
15.4.8
The UIPCR registers show the current state and the change-of-state for the CTS pin. (Note: not available
on UART2).
15.4.9
The UART auxiliary control registers control the input enable.

1 A change-of-state (high-to-low or low-to-high transition), lasting longer than 25–50 μs has occurred at the CTS input.
0 No change-of-state has occurred since the last time the CPU read the UART Input Port Change Register (UIPCR).
Current State
Starting two serial clock periods after reset, the CTS bit reflects the state of the CTS pin. If the CTS pin is detected as
asserted at that time, the COS bit is set, which initiates an interrupt if the Input Enable Control (IEC) bit of the UACR
register is enabled.
1 The current state of the CTS input is logic one.
0 The current state of the CTS input is logic zero.
Note: Not available on UART2
Change-of-State
MBAR + $210 (UIPCR1)
MBAR2 + $C10 (UIPCR2)
When this bit is set, the UART Auxiliary Control Register (UACR) can be programmed to generate an interrupt to
the CPU.
A read of the UIPCR also clears the UART Interrupt Status Register (UISR)COS bit.
