PRODUCTION DATA
Most peripherals can be operational in LPM3 if clocked by ACLK. Some modules are 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 reduce the idle current adder, certain peripherals are grouped together. To achieve optimal current consumption, use modules within one group and limit the number of groups with active modules. Table 9-3 lists the peripheral groups. Modules not listed in this table are either already included in the standard LPM3 current consumption 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 current parameters in Section 8 for details.
