Most peripherals can be activated to be operational in LPM3 if clocked by ACLK. Some modules are even operational in LPM4 because they do not require a clock to operate (for example, the comparator). Activating a peripheral in LPM3 or LPM4 increases the current consumption due to its active supply current contribution but also due to an additional idle current. To limit the idle current adder certain peripherals are group together. To achieve optimal current consumption try to use modules within one group and to limit the number of groups with active modules. Table 6-3 lists the group for each peripheral. Modules not listed in this table are either already included in the standard LPM3 current consumption specifications or cannot be used in LPM3 or LPM4.
The idle current adder is very small at room temperature (25°C) but increases at high temperatures (85°C). See the IIDLE parameters in Section 5.7 for details.
