6.4 Operating Modes
The MCUs have one active mode and seven 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.
Software can configure the following operating modes:
• Active mode (AM)
– All clocks are active
• Low-power mode 0 (LPM0)
– CPU is disabled
– ACLK and SMCLK remain active, MCLK is disabled
– FLL loop control remains active
• Low-power mode 1 (LPM1)
– CPU is disabled
– FLL loop control is disabled
– ACLK and SMCLK remain active, MCLK is disabled
• Low-power mode 2 (LPM2)
– CPU is disabled
– MCLK, FLL loop control, and DCOCLK are disabled
– DC generator of the DCO remains enabled
– ACLK remains active
• Low-power mode 3 (LPM3)
– CPU is disabled
– MCLK, FLL loop control, and DCOCLK are disabled
– DC generator of the DCO is disabled
– ACLK remains active
• Low-power mode 4 (LPM4)
– CPU is disabled
– ACLK is disabled
– MCLK, FLL loop control, and DCOCLK are disabled
– DC generator of the DCO is disabled
– Crystal oscillator is stopped
– Complete data retention
• Low-power mode 3.5 (LPM3.5)
– Internal regulator disabled
– No data retention
– RTC enabled and clocked by low-frequency oscillator
– Wake-up signal from RST/NMI, RTC_B, P1, P2, P3, and P4
• Low-power mode 4.5 (LPM4.5)
– Internal regulator disabled
– No data retention
– Wake-up signal from RST/NMI, P1, P2, P3, and P4
