Description
32 kHz clock oscillator select:
0 – 32.768 kHz crystal oscillator
1 – 34 kHz low power RC oscillator
Main clock oscillator select:
0 – 26/48 MHz crystal oscillator
1 – 13 MHz HF RC oscillator
This setting will only take effect when the selected oscillator is
powered up and stable. If the selected oscillator is not powered up,
then writing this bit will power it up.
Timer ticks output setting. The value of TICKSPD cannot be higher
than CLKSPD.
