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:

D Active mode AM;

−

All clocks are active

D Low-power mode 0 (LPM0);

−

CPU is disabled

ACLK and SMCLK remain active. MCLK is disabled

D 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

D Low-power mode 2 (LPM2);

−

MCLK and SMCLK are disabled

DCO’s dc-generator remains enabled

ACLK remains active

D Low-power mode 3 (LPM3);
