TSEG22–TSEG10 — Time Segment
The CBTR1 register can only be written if the SFTRES bit in the
MSCAN08 module control register is set.
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
The bit time is determined by the oscillator frequency, the baud rate
prescaler, and the number of time quanta (T
