Bit 15 – SNTEN SENTx Enable bit

ValueDescription
1

SENTx is enabled.
0

SENTx is disabled.

Bit 13 – SNTSIDL SENTx Stop in Idle Mode bit

ValueDescription
1 Discontinues module operation when the device enters Idle mode.
0 Continues module operation in Idle mode.

Bit 11 – RCVEN SENTx Receive Enable bit

ValueDescription
1 SENTx operates as a receiver.
0 SENTx operates as a transmitter (sensor).

Bit 10 – TXM  SENTx Transmit Mode bit(1)

ValueDescription
1 SENTx transmits the data frame only when triggered using the SYNCTXEN status bit.
0

SENTx transmits the data frames continuously while SNTEN = 1.

Bit 9 – TXPOL  SENTx Transmit Polarity bit(1)

ValueDescription
1 SENTx data output pin is low in the Idle state.
0 SENTx data output pin is high in the Idle state.

Bit 8 – CRCEN CRC Enable bit

Module in Receive Mode (RCVEN = 1):

1 = SENTx performs CRC verification on received data using the preferred J2716 method.

0 = SENTx does not perform CRC verification on received data.

1 = SENTx automatically calculates CRC using the preferred J2716 method.

0 = SENTx does not calculate CRC.

Bit 7 – PPP Pause Pulse Present bit

ValueDescription
1 SENTx is configured to transmit/receive SENT messages with a pause pulse.
0 SENTx is configured to transmit/receive SENT messages without a pause pulse.
