Common Control Register 1
| CTSE | CTS Enable 0 (0): CTS function is disabled (RTS output function is enabled). 1 (1): CTS function is enabled. |
| CTSPEN | CTS external pin Enable 0 (0): Alternate setting to use CTS and RTS functions as either one pin 1 (1): Dedicated setting for separately using CTS and RTS functions with 2 pins |
| SPB2DT | Serial port break data select 0 (0): When TINV is 0, Low level is output in TXDn pin. When TINV is 1, High level is output in TXDn pin. 1 (1): When TINV is 0, High level is output in TXDn pin. When TINV is 1, Low level is output in TXDn pin. |
| SPB2IO | Serial port break I/O 0 (0): The value of SPB2DT bit is not output in TXDn pin. 1 (1): The value of SPB2DT bit is output in TXDn pin. |
| PE | Parity Enable 0 (0): When transmitting: Do not add parity bit When receiving: Do not check parity bit 1 (1): When transmitting: Add parity bit When receiving: Check parity bit |
| PM | Parity Mode 0 (0): Selects even parity 1 (1): Selects odd parity |
| TINV | TXD invert 0 (0): Transmit data is not inverted and output to TXDn. 1 (1): Transmit data is inverted and output to TXDn. |
| RINV | RXD invert 0 (0): Received data from RXDn is not inverted and input. 1 (1): Received data from RXDn is inverted and input. |
| SPLP | Loopback Control 0 (0): Normal mode 1 (1): Loopback mode |
| SHARPS | Half-duplex communication select 0 (0): TXDn pin, RXDn pin independent 1 (1): TXDn / RXDn pin combination use (Half-duplex communication using TXDn pin) |
| NFCS | Noise Filter Clock Select 0 (000): The base clock signal divided by 1. 0 (others): Setting prohibited. 1 (001): The on-chip baud rate generator source clock divided by 1. 2 (010): The on-chip baud rate generator source clock divided by 2. 3 (011): The on-chip baud rate generator source clock divided by 4. 4 (100): The on-chip baud rate generator source clock divided by 8. |
| NFEN | Digital Noise Filter Function Enable 0 (0): In Asynchronous, Manchester, Simple LIN mode: Disable noise cancellation function for RXDn input signal In Simple IIC mode: Disable noise cancellation function for SCLn and SDAn input signals 1 (1): In Asynchronous, Manchester, Simple LIN mode: Enable noise cancellation function for RXDn input signal In Simple IIC mode: Enable noise cancellation function for SCLn and SDAn input signals |
