CTS Trigger Level
This bit can change the CTS trigger level to send TX_FIFO data.
0= high level triggered
1= low level triggered
Reserved
CTS Pin Status (Read Only)
This bit is the pin status of CTS.
Reserved
Detect CTS State Change Flag (Read Only)
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.
NOTE: This bit is read only, but can be cleared by writing ‘1’ to it.
