Serial Mode Register for Non-Smart Card Interface Mode (SCMR.SMIF = 0)
| CKS | Clock Select 0 (00): PCLK clock (n = 0) 1 (01): PCLK/4 clock (n = 1) 2 (10): PCLK/16 clock (n = 2) 3 (11): PCLK/64 clock (n = 3) |
| MP | Multi-Processor Mode 0 (0): Disable multi-processor communications function 1 (1): Enable multi-processor communications function |
| STOP | Stop Bit Length 0 (0): 1 stop bit 1 (1): 2 stop bits |
| PM | Parity Mode 0 (0): Even parity 1 (1): Odd parity |
| 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 |
| CHR | Character Length 0 (0): SCMR.CHR1 = 0: Transmit/receive in 9-bit data length SCMR.CHR1 = 1: Transmit/receive in 8-bit data length (initial value) 1 (1): SCMR.CHR1 = 0: Transmit/receive in 9-bit data length SCMR.CHR1 = 1: Transmit/receive in 7-bit data length |
| CM | Communication Mode 0 (0): Asynchronous mode or simple IIC mode 1 (1): Clock synchronous mode or simple SPI mode |
