3.5.9 System PLL clock source select register
The reset value given in
Table 15.
This register selects the clock source for the system PLL. The SYSPLLCLKUEN register
(see
Remark: When switching clock sources, both clocks must be running before the clock
source is updated.
Remark: When using the C_CAN controller with baudrates above 100 kbit/s, the system
oscillator must be selected.
