MSCAN Controller (MSCAN08)
24.14.4 MSCAN08 Bus Timing Register 1
Advance Information

NOTE:
Address:
BRP5–BRP0 — Baud Rate Prescaler
The CBTR0 register can be written only if the SFTRES bit in the
MSCAN08 module control register is set.
SAMP — Sampling
1. In this case PHASE_SEG1 must be at least 2 time quanta.

These bits determine the time quanta (T
up the individual bit timing, according
This bit determines the number of serial bus samples to be taken per
bit time. If set, three samples per bit are taken, the regular one
(sample point) and two preceding samples, using a majority rule. For
higher bit rates, SAMP should be cleared, which means that only one
sample will be taken per bit.
