During stop mode, all clocks including the main clock are turned off.
2.3 On Chip Oscillator Clocks.
The micons contain an on-chip oscillating circuitry that generates two clock
sources: High speed on chip oscillator and Low speed on chip oscillator. These
oscillators are selected by the bit, HR01 of HR0 register.
2.4 Low Speed On chip Oscillator:
The clock derived from the low-speed on-chip
oscillator is used as the clock source for the
CPU clock, peripheral function clocks, fRING,
fRING128 and fRING-S. After reset, the on-
chip clock derived from low-speed on-chip
oscillator with the division of 8 is selected
as the CPU clock.
