#24931 - RE: CAN communications
A basic approach is this:
Divide the XTL Frequency by 2 for X2 mode = off.
BRP is a divider (XTL/2) / (BRP+1) gives the "Quantafrequency".
exp.11.0592MHz -> 5.5MHz BRP=1 -> 2.75MHz Quantafreq. Now this is 11 x 250k
11 Quantas are formed:
PRS+1 (=7) + PHS1+1 (=1) PHS0+1 (=2) + 1 (fix) = 11

Leaving PHS1 / PHS0 small gives a sampling Time somewhere in the last third..87% of a Bit Time which is recommended by CiA

If you want more details study the manual :)
