After timer n has been programmed to capture rising edge events, it can
be used under software control to generate 16-bit time stamps which can
be stored with the received message.

circuitry and its interaction with the clock generation module (CGM).
With this flexible clocking scheme the MSCAN08 is able to handle CAN
bus rates ranging from 10 kbps up to 1 Mbps.
The clock source bit (CLKSRC) in the MSCAN08 module control register
(CMCR1) (see
defines whether the MSCAN08 is connected to the output of the crystal
oscillator or to the PLL output.
