Low power measurement mode
In low power measurement mode SCP1000 stays in standby mode until measurement is externally
triggered. The measurement is triggered with rising edge of TRIG pin or by writing 0x0C to
OPERATION register. Low power measurement can be triggered after start-up and power down. If
some other measurement mode is activated, see section 2.2.2.1 for details of switching between
measurement modes.
The default measurement resolution for low power mode is 17 bits. Resolution can be configured to
15 bit or 17 bit mode through indirect CFG register (see section 3.3). The CFG register contents
are presented in Table 8 below.
Table 8. Recommended CFG register contents.
SCP1000 operation parameters in low power measurement mode are presented in Table 9 below.
