Re-synchronization is performed according to the following
rules:
If the magnitude of e is less or equal to the programmed
value of SJW, re-synchronization will have the same effect
as hard synchronization.
If e > SJW, the time segment 1 will be lengthened by the
value of the SJW (see Figure 53).
If e < -SJW, the time segment 2 will be shortened by the
value SJW (see Figure 54).
20.2.4
The CAN prescaler (PSC) is shown is Figure 55. It divides
the CKI input clock by the value defined in the CTIM register.
The resulting clock is called time quanta clock and defines
the length of one time quanta (tq).
Please refer to CAN Timing Register (CTIM) on page 111 for
a detailed description of the CTIM register.
Note:
PSC is the value of the clock prescaler. TSEG1 and
TSEG2 are the length of time segment 1 and 2 in tq.
The resulting bus clock can be calculated by the equation:
Clock Generator
The values of PSC and TSEG 1 and 2 are specified by the
contents of the registers PSC, TSEG1 and TSEG2 as fol-
lows:
PSC = PSC[5:0] + 2
TSEG1 = TSEG1[3:0] + 1
TSEG2 = TSEG2 [2 : 0] + 1
