Serial Data Interface
A sensor for X-axis and Y-axis is embedded independently.
(As for sensitivity direction of X-axis and Y-axis, see the following figure.)
The amplifier amplifies a signal from the magnetic sensor output.
The sensor is a thermal sensor for the compensation of temperature characteristics of the
magnetic sensor.
The ADC converts magnetic sensor output and temperature sensor output into digital data.
The clock generation section supplies clocks for ADC and digital circuits.
The section detects a rising of the power–on and initializes circuits.
The coil is used when the magnetic sensor cannot give original characteristics due to receiving
strong magnetic field.
Generating magnetic field by the initialization coil initializes the magnetic sensor
characteristics.
The initialization coil is operated by setting Config register CONFR [3:0].
