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
-- FLL+ loop control remains active
D Low-power mode 1 (LPM1)
-- CPU is disabled
-- ACLK and SMCLK remain active
-- 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
