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.

After reset, the

on-chip clock derived

from low-speed on-chip

oscillator

with the

division of 8 is

selected as the

CPU clock.
