IDLE mode
The IDLE mode can be entered from any run mode. The main oscillator must
be operating. IDLE mode can not be entered if the CPU is clocked by the sub
or ring oscillator.
In IDLE mode, the clock distribution is stopped (refer to the “Standby” switches
in Figure 4-1, “Block diagram of the Clock Generator,” on page 130).
The states of all clock sources, that means, sub and ring oscillator as well as
SSCG and PLL, remain unchanged. If a clock source was operating before
entering IDLE mode, it continues operating.
Clock Generator status in IDLE mode
The IDLE mode can be released by
• the unmasked maskable interrupts INTPn, INTCnWUP, INTWTnUV,
• NMI0, NMIWDT
• RESET, RESPOC, RESWDT, RESCMM, RESCMS
On IDLE mode release, the CPU clock and peripheral clocks are supplied by
the main oscillator.
