Disabling the 80 MHz RC oscillator
When the 80 MHz RC oscillator is not used by the CPU or by any peripheral for a long time,
it is recommended to power it down by setting CRMU.CCR0.ANA_PD80M to 1.
When powering down the 80 MHz RC oscillator, the software must change the CPU clock to
another source (32 kHz or external) first (CRMU.CCR0.HS_OSC_SEL = 0b01 for example),
and then execute a second CRMU register access to power down the oscillator
(CRMU.CCR0.ANA_PD80M = 1).
When powering up the 80 MHz RC oscillator, the software can power up the oscillator
(CRMU.CCR0.ANA_PD80M = 0) and change the CPU clock to the 80 MHz RC oscillator
source at the same time (CRMU.CCR0.HS_OSC_SEL = 0b00).
