a. If used as PLL input. APLL input frequency has to be at minimum 12 MHz, regardless which clock is routed
to APLL.
b. If used as direct clock source bypassing the APLL, the user should take care that resulting core clock fre-
quency is above or equal to MCU bus interface clock. Be aware of tolerances!
c. The video interface is designed to achieve 54 MHz but there is a side condition that video clock should be
smaller than half of core clock.
