Operating Modes
The MSP430 has one active mode and seven software selectable low-power modes of operation. An interrupt
event can wake up the device from any of the low-power modes, service the request, and restore back to the
low-power mode on return from the interrupt program.
The following seven operating modes can be configured by software:
Active mode (AM)
All clocks are active
Low-power mode 0 (LPM0)
CPU is disabled
ACLK and SMCLK remain active, MCLK is disabled
FLL loop control remains active
Low-power mode 1 (LPM1)
CPU is disabled
FLL loop control is disabled
ACLK and SMCLK remain active, MCLK is disabled
Low-power mode 2 (LPM2)
CPU is disabled
MCLK, FLL loop control, and DCOCLK are disabled
DCO's dc generator remains enabled
ACLK remains active
Low-power mode 3 (LPM3)
CPU is disabled
MCLK, FLL loop control, and DCOCLK are disabled
DCO's dc generator is disabled
ACLK remains active
Low-power mode 4 (LPM4)
CPU is disabled
ACLK is disabled
MCLK, FLL loop control, and DCOCLK are disabled
DCO's dc generator is disabled
Crystal oscillator is stopped
Complete data retention
Low-power mode 3.5 (LPM3.5)
Internal regulator disabled
No data retention
RTC enabled and clocked by low-frequency oscillator
Wakeup from RST/NMI, RTC_B, P1, P2, P3, and P4
Low-power mode 4.5 (LPM4.5)
Internal regulator disabled
No data retention
Wakeup from RST/NMI, RTC_B, P1, P2, P3, and P4
