Description

Common Control Register 3

Fields

CPHA

Clock Phase Select

0 (0): Data is sampled at an odd edge and changes at an even edge. (Clock is delayed.)

1 (1): Data changes at an odd edge and is sampled at an even edge. (Clock is not delayed)

CPOL

Clock Polarity Select

0 (0): SCKn in idle state is 0.

1 (1): SCKn in idle state is 1.

BPEN

Synchronizer bypass enable

0 (0): Synchronizer circuit is not bypassed.

LSBF

LSB First select

0 (0): MSB first

SINV

Transmitted/Received Data Invert

0 (0): TDR contents are transmitted to TSR as they are. RSR contents are stored to RDR as they are.

1 (1): TDR contents are inverted before being transmitted to TSR. RSR contents are inverted and stored to RDR.

STP

Stop Bit Length

0 (0): 1 stop bit / Break Delimiter length is 1bit
