UART Control Register 1
| PT | Parity Type 0 (0): Even parity. 1 (1): Odd parity. |
| PE | Parity Enable 0 (0): Parity function disabled. 1 (1): Parity function enabled. |
| ILT | Idle Line Type Select 0 (0): Idle character bit count starts after start bit. 1 (1): Idle character bit count starts after stop bit. |
| WAKE | Receiver Wakeup Method Select 0 (0): Idle line wakeup. 1 (1): Address mark wakeup. |
| M | 9-bit or 8-bit Mode Select 0 (0): Normal-start + 8 data bits (MSB/LSB first as determined by MSBF) + stop. 1 (1): Use-start + 9 data bits (MSB/LSB first as determined by MSBF) + stop. |
| RSRC | Receiver Source Select 0 (0): Selects internal loop back mode. The receiver input is internally connected to transmitter output. 1 (1): Single wire UART mode where the receiver input is connected to the transmit pin input signal. |
| UARTSWAI | UART Stops in Wait Mode 0 (0): UART clock continues to run in Wait mode. 1 (1): UART clock freezes while CPU is in Wait mode. |
| LOOPS | Loop Mode Select 0 (0): Normal operation. 1 (1): Loop mode where transmitter output is internally connected to receiver input. The receiver input is determined by RSRC. |
