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 available to modules.

FLL+ loop control remains active.

Low-power mode 1 (LPM1)

CPU is disabled.

ACLK and SMCLK remain active, MCLK is available to modules.

FLL+ loop control is disabled.

Low-power mode 2 (LPM2)

MCLK, FLL+ loop control, and DCOCLK are disabled.

DCO dc generator remains enabled.

ACLK remains active.

Low-power mode 3 (LPM3)

CPU is disabled.

DCO dc generator is disabled.

ACLK remains active.

Low-power mode 4 (LPM4)

CPU is disabled.
