SCI control register 1 (SCICR1)

2NF

Noise flag

In LIN master mode (LINE bit = 1 and LSLV bit = 0) this bit has the same function as in

SCI mode, please refer to SCI status register (SCISR) on page 152.

In LIN slave mode (LINE bit = 1 and LSLV bit = 1) this bit has no meaning.

1FE

Framing error

In LIN slave mode, this bit is set only when a real framing error is detected (if the stop

bit is dominant (0) and at least one of the other bits is recessive (1). It is not set when

a break occurs, the LHDF bit is used instead as a break flag (if the LHDM bit = 0). It is

cleared by a software sequence (an access to the SCISR register followed by a read

to the SCIDR register).

0: No framing error

1: Framing error detected

0PE

Parity error

This bit is set by hardware when a LIN parity error occurs (if the PCE bit is set) in

receiver mode. It is cleared by a software sequence (a read to the status register

followed by an access to the SCIDR data register). An interrupt is generated if PIE = 1

in the SCICR1 register.

0: No LIN parity error

1: LIN parity error detected

Bits 7:4 have the same function as in SCI mode, please refer to SCI status register (SCISR) on page 152.

Bit Name

Function

Receive data bit 8

This bit is used to store the 9th bit of the received word when M = 1.

6T8

Transmit data bit 8

This bit is used to store the 9th bit of the transmitted word when M = 1.

5SCID

Disabled for low power consumption

When this bit is set the SCI prescalers and outputs are stopped and the end of the

current byte transfer in order to reduce power consumption.This bit is set and cleared

by software.

0: SCI enabled

1: SCI prescaler and outputs disabled
