Note: R = Read access; W = Write access; value following dash (–) = value after reset
Bits 15–8 Reserved.
Bits 7–0 BRP. Baud Rate Prescaler
Bits 7:0 of this field specify the duration of a time quantum (TQ) in CAN module
system clock units. The length of one TQ is defined by:
TQ
BRP 1
I
CLK
=
+
where I
CLK
is the frequency of the CAN module system clock,which is the same
as CLKOUT.
