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

–
