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)
-- CPU is disabled.
-- MCLK and SMCLK are disabled.
-- DCO’s dc generator remains enabled.
-- ACLK remains active.
D Low-power mode 3 (LPM3)
-- CPU is disabled.
-- MCLK and SMCLK are disabled.
-- DCO’s dc generator is disabled.
-- ACLK remains active.
D Low-power mode 4 (LPM4)
