operating modes

The MSP430 has one active mode and five software-selectable low-power modes of operation. An interrupt

event can wake up the device from any of the five low-power modes, service the request, and restore back to

the low-power mode on return from the interrupt program.

The following six 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

Low-power mode 1 (LPM1);

CPU is disabled

ACLK and SMCLK remain active. MCLK is disabled

DCO’s dc-generator is disabled if DCO not used in active mode

Low-power mode 2 (LPM2);

CPU is disabled

MCLK and SMCLK are disabled

DCO’s dc-generator remains enabled

ACLK remains active

Low-power mode 3 (LPM3);

CPU is disabled

MCLK and SMCLK are disabled

DCO’s dc-generator is disabled

ACLK remains active

Low-power mode 4 (LPM4);

CPU is disabled

ACLK is disabled

MCLK and SMCLK are disabled
