Clock Doubler
This device contains a frequency doubler that doubles the frequency of the oscillator selected to operate
the main microcontroller core. The details of how to select either the high speed oscillator or low speed
oscillator are described in, Power Saving Features. When the high speed oscillator connected to CKI
operates at 10 MHz, the internal clock frequency is 20 MHz, resulting in an instruction cycle time of 0.5 s.
When the 32 kHz oscillator connected to L0 and L1 is selected, the internal clock frequency is 64 kHz,
resulting in an instruction cycle of 152.6 s. The output of the clock doubler is called MCLK and is
referenced in many places within this document.
