SCMR selects SCI functions and its format.

Bit Bit Name

Initial

Value R/W Description

7 to 4 — All 1 R Reserved

These bits are always read as 1 and cannot be

modified.

3 SDIR 0 R/W 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.

2 SINV 0 R/W 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. Receive

data is stored as it is in RDR.

1: TDR contents are inverted before being transmitted.

Receive data is stored in inverted form in RDR.

1 — 1 R Reserved

This bit is always read as 1 and cannot be modified.

0 SMIF 0 R/W Serial Communication Interface Mode Select:

0: Normal asynchronous or clocked synchronous mode
