CAN BIT TIMING REGISTER 0 (CBTR0)
This register can only be accessed by the software
when the CAN hardware is in configuration mode.
Read / Write
Reset Value: 0000 0000 (00h)
Bit 7:6 SJW[1:0] Resynchronization Jump Width
These bits define the maximum number of time
quanta the CAN hardware is allowed to lengthen
or shorten a bit to perform the resynchronization.
Bit 5:0 BRP[5:0] Baud Rate Prescaler
These bits define the length of a time quantum.
tq = (BRP+1)/fsys
