“Programming
16.3.3
The TouCAN module uses three 8-bit registers to set up the bit timing parameters required by the CAN
protocol. Control registers one and two (CANCTRL1, CANCTRL2) contain the PROPSEG, PSEG1,
PSEG2, and the RJW fields that allow configuration of the bit timing parameters. The prescaler divide
register (PRESDIV) allows selection of the ratio used to derive the serial clock (S-clock) from the system
clock. The time quanta clock operates at the S-clock frequency.
