Clocks and Power Control
The system clocks GCLK1 and GCLK2 frequency is:
Therefore, the complete equation for determining the system clock frequency is:
8-12
System Frequency=
where FREQsysmax = VCOOUT/2
CLKOUT does not have a 50% duty cycle when the general system clock is
divided. The CLKOUT wave form is the same as that of GCLK2_50.
GCLK1 Divide by 1
GCLK2 Divide by 1
GCLK1 Divide by 2
GCLK2 Divide by 2
GCLK1 Divide by 4
GCLK2 Divide by 4
