1. Runs only when CC-ADC is enabled, or OSI is enabled and RCOSC_SLOW is selected as source for OSI.
2. Runs only when CC-ADC is enabled
3. Address Match and Bus Connect/Disconnect Wake-up only
4. Discharge FET must be switched off for Charger Detect to be enabled.
5. VREGMON interrupt (Regulator Operation Condition Warning) not available.
Idle Mode
ADC Noise Reduction
Power-save Mode
Active modules in different Sleep Modes (Continued)

When the SM2:0 bits are written to 000, the SLEEP instruction makes the MCU enter Idle mode,
stopping the CPU but allowing all peripheral functions to continue operating. This sleep mode
basically halts clk
MCU to wake up from external triggered interrupts as well as internal ones like the Timer Over-
flow interrupt.
When the SM2:0 bits are written to 001, the SLEEP instruction makes the MCU enter ADC
Noise Reduction mode, stopping the CPU but allowing the Voltage ADC (V-ADC), Voltage Reg-
ulator Monitor (VREGMON), Watchdog Timer (WDT), Coulomb Counter (CC), Current Battery
Protection (CBP), Slow RC Oscillator (RCOSC_SLOW) (if CC is enabled), and the Ultra Low
Power RC Oscillator (RCOSC_ULP) to continue operating. This sleep mode basically halts
clk
This improves the noise environment for the Voltage ADC, enabling higher accuracy on
measurements.
When the SM2:0 bits are written to 011, the SLEEP instruction makes the MCU enter Power-
save mode. In this mode, the internal Fast RC Oscillator (RCOSC_FAST) is stopped, while
Watchdog Timer (WDT), Coulomb Counter (CC), Current Battery Protection (CBP) , Slow RC
Oscillator (RCOSC_SLOW) (if CC is enabled), and the Ultra Low Power RC Oscillator
(RCOSC_ULP) continue operating.
This mode will be the default mode when application software does not require operation of
CPU, Flash or any of the peripheral units running at the Fast internal Oscillator (RCOSC_FAST).
