Operating Modes

The MSP430 has one active mode and six 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 and 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 4.5 (LPM4.5)

– Internal regulator disabled
