STR71X CLOCK CONFIGURATIONS EASY SETUP

As an example, the table 1 lists the different standard bitrates of the CAN with their timing pa-

rameters with PCLK1 = 20MHz.

With:

NTQ: TSEG1+TSEG2+3

TSEG1: Time Segment before the sampling point minus Sync_seg

TSEG2: Time Segment after the sampling point

SJW: Synchronization Jump Width

BRP: Baud Rate Prescaler
