SAM=THE_BUS_IS_SAMPLED_O

Description

Bus Timing. Can only be written when RM in CANMOD is 1.

Fields

BRP

Baud Rate Prescaler. The APB clock is divided by (this value plus one) to produce the CAN clock.

RESERVED

Reserved. Read value is undefined, only zero should be written.

SJW

The Synchronization Jump Width is (this value plus one) CAN clocks.

TESG1

The delay from the nominal Sync point to the sample point is (this value plus one) CAN clocks.

TESG2

The delay from the sample point to the next nominal sync point is (this value plus one) CAN clocks. The nominal CAN bit time is (this value plus the value in TSEG1 plus 3) CAN clocks.

SAM

Sampling

0 (THE_BUS_IS_SAMPLED_O): The bus is sampled once (recommended for high speed buses)

1 (THE_BUS_IS_SAMPLED_3): The bus is sampled 3 times (recommended for low to medium speed buses to filter spikes on the bus-line)

RESERVED

Reserved. Read value is undefined, only zero should be written.
