CAN Controller Software Initialization
The very first step of the initialization is the CAN controller input clock selection. A divide-by-2
prescaler is enabled by default after reset (
figure 16
). Setting bit CMOD (SYSCON.3) disables the
prescaler. The purpose of the prescaler selection is:
– to ensure that the CAN controller is operable when
f
osc
is over 10 MHz (bit CMOD =0)
– to achieve the maximum CAN baudrate of 1 Mbaud when
f
osc
is 8 MHz (bit CMOD=1)
.
