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 available to modules.
− FLL+ loop control remains active.
D Low-power mode 1 (LPM1)
− CPU is disabled.
− ACLK and SMCLK remain active. MCLK is available to modules.
− FLL+ loop control is disabled.
D Low-power mode 2 (LPM2)
− CPU is disabled.
− MCLK, FLL+ loop control, and DCOCLK are disabled.
− DCO’s dc generator remains enabled.
− ACLK remains active.
D 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.
D 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.
− Crystal oscillator is stopped.
