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 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
– DCO's dc generator is disabled
– Crystal oscillator is stopped
