10.2
When the CPU enters sleep mode the CPUCLK Select (Bit [0],
Table 10-3
) is forced to the Internal Oscillator, and the oscil-
lator is stopped. When the CPU comes out of sleep mode it is
running on the internal oscillator. The internal oscillator
recovery time is three clock cycles of the Internal 32-KHz Low-
power Oscillator.
If the system requires the CPU to run off the external clock
after awaking from sleep mode, firmware will need to switch
the clock source for the CPU.

Reset
The microcontroller supports two types of resets: Power-on
Reset (POR) and Watchdog Reset (WDR). When reset is
initiated, all registers are restored to their default states and all
interrupts are disabled.
The occurrence of a reset is recorded in the System Status and
Control Register (CPU_SCR). Bits within this register record
the occurrence of POR and WDR Reset respectively. The
firmware can interrogate these bits to determine the cause of
a reset.
The microcontroller resumes execution from Flash address
0x0000 after a reset. The internal clocking mode is active after
a reset, until changed by user firmware.
Note
The CPU clock defaults to 3 MHz (Internal 24 MHz Oscil-
lator divide-by-8 mode) at POR to guarantee operation at the
low V
CC
that might be present during the supply ramp.
