Operation
Power Mode
The RT3000 has three different power modes: power down
mode, normal mode and high resolution mode to offer the
customer different power consumption and effective
resolution options.
The transitions between the power modes are illustrated
in figure below
VDD Power On
CTRL1_REG[7:4] = "0000"
Power Down
NOR. Mode
(Normal power
consumption and
resolution)
HR Mode
(Highest power
consumption and
resolution)
CTRL4_REG[3] = "0"
CTRL4_REG[3] = "1"
Different mode switch time : 12/ODR ms
When the RT3000 is in power-down mode, almost all
internal blocks of the device are switched off except digital
interfaces (I2C) are still active to allow communication with
the device. The configuration registers content is preserved
and output data registers keeping the last data sampled
in memory before going into power-down mode.
In normal mode or high resolution mode, its depending
on customers application to set related register.
Self-Test
The RT3000 has the self-Test feature for the sensor
functionality check by applying electrostatic force to the
sensor element. A static offset of the acceleration data
could be observed when the self-test activate. The
acceleration measurement range should be set to 2g
before self-test is enabled. The self-test function is off
when the self-test bit (STEN) is programmed to 0. When
the self-test bit is programmed to 1an actuation force
is applied to the sensor, simulating a definite input
acceleration. Table 1 shows the typical offset differences
of self-test for each axes.
