12.13.4 MSCAN08 Bus Timing Register 1
SAMP — Sampling
TSEG22–TSEG10 — Time Segment
1. In this case PHASE_SEG1 must be at least 2 time quanta.
Freescale Semiconductor
TSEG13
1. This setting is not valid. Please refer to
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.
Time segments within the bit time fix the number of clock cycles per bit time and the location of the
sample point. Time segment 1 (TSEG1) and time segment 2 (TSEG2) are programmable as shown in
