Description

Serial Mode Register (SCMR.SMIF = 0)

Fields

CKS

Clock Select

0 (00): PCLK clock

1 (01): PCLK/4 clock

2 (10): PCLK/16 clock

3 (11): PCLK/64 clock

MP

Multi-Processor Mode(Valid only in asynchronous mode)

0 (0): Multi-processor communications function is disabled

1 (1): Multi-processor communications function is enabled

STOP

Stop Bit Length(Valid only in asynchronous mode)

0 (0): 1 stop bit

1 (1): 2 stop bits

PM

Parity Mode (Valid only when the PE bit is 1)

0 (0): Selects even parity

1 (1): Selects odd parity

PE

Parity Enable(Valid only in asynchronous mode)

0 (0): Parity bit addition is not performed (transmitting) / Parity bit checking is not performed ( receiving )

1 (1): The parity bit is added (transmitting) / The parity bit is checked (receiving)

CHR

Character Length(Valid only in asynchronous mode)

0 (0): Transmit/receive in 9-bit data length(SCMR.CHR1=0) / in 8bit data length(SCMR.CHR1=1)

1 (1): Transmit/receive in 9-bit data length(SCMR.CHR1=0) / in 7bit data length(SCMR.CHR1=1)

CM

Communications Mode

0 (0): Asynchronous mode or simple I2C mode

1 (1): Clock synchronous mode
