Therefore the … WebA 30 MHz CAN clock gives us Tpclk of 33.33 ns. 1.67 μS / 33.33 nS gives us almost exactly 50 clock ticks per bit time. A good rule of thumb is to have your sampling point at 70-80% of the nominal bit time. More towards 80% the higher the baud rate. So let's set BRP[9:0] to 4 which gives us: Tq = (4 + 1) x 33.33 ns = 166.65 ns
