CTS Trigger Level (not available in UART2 channel)
This bit can change the CTS trigger level.
1= high level triggered
0= low level triggered
Reserved
CTS Pin Status (Read Only) (not available in UART2 channel)
This bit is the pin status of CTS.
Reserved
Detect CTS State Change Flag (Read Only) (not available in UART2 channel)
This bit is set whenever CTS input has change state, and it will generate Modem
interrupt to CPU when UA_IER [MODEM_IEN] is set to 1.
Software can write 1 to clear this bit to zero
