Description
Reserved
These bits are always read as 1 and cannot be
modified.
Data Transfer Direction
Selects the serial/parallel conversion format.
0: TDR contents are transmitted with LSB-first.
Receive data is stored as LSB first in RDR.
1: TDR contents are transmitted with MSB-first.
Receive data is stored as MSB first in RDR.
The SDIR bit is valid only when the 8-bit data format
is used for transmission/reception; when the 7-bit
data format is used, data is always
transmitted/received with LSB-first.
Data Invert
Specifies inversion of the data logic level. The SINV
bit does not affect the logic level of the parity bit.
When the parity bit is inverted, invert the O/E bit in
SMR.
0: TDR contents are transmitted as they are.
1: TDR contents are inverted before being
