Idle Currents of Peripherals in LPM3 and LPM4
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 6-3 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 5 for details.

Interrupt Vector Table and Signatures
The interrupt vectors, the power-up start address, and signatures are in the address range 0FFFFh to
0FF80h. Figure 6-2 summarizes the content of this address range.
Figure 6-2. Interrupt Vectors, Signatures and Passwords
The power-up start address or reset vector is at 0FFFFh to 0FFFEh. It contains the 16-bit address pointing
to the start address of the application program.
The interrupt vectors start at 0FFFDh and extend to lower addresses. Each vector contains the 16-bit
address of the appropriate interrupt-handler instruction sequence. Table 6-4 shows the device-specific
interrupt vector locations.
The vectors programmed into the address range from 0FFFFh to 0FFE0h are used as BSL password (if
enabled by the corresponding signature).
