6.2) Description of Control Register (Volatile Memory)

a) Adjustment mode (Register name: CM1)

This register is used to adjust the AK8999A reference voltage and pressure sensor's offset, span,

offset temperature drift and sensitivity temperature drift including those of the AK8999A.

In addition, the value of the register returns to the initial value on the following conditions.

■ At the power up

■ When CSCLK = Low is maintained 0.5msec or more

■ When ETST[0] is set to "L"

Address : 00 hex D[3:0] = AM[3:0]

(This is not a nonvolatile EEPROM, but a volatile register.)

D[7:0] Symbol Mode setup Description

D[7:4] Reserved Setup prohibited

D[3:0] AM[3:0] IC adjustment mode

0000 (default)

0001 AVR VREF adjustment The VREF voltage is output at the VOUT pin.

0010 AIR IREF adjustment The IREF current is output at the VOUT pin.

0011 AFR OSC adjustment

Input the fixed period of High level (2.0msec) from the

CSCLK pin. The count value in the internal counter is

stored in the register.

0100 ATO VTMP adjustment

The VTMP voltage is output at the VOUT pin.

Adjust this voltage so that it matches the VREF

voltage at 25C.

0101 ADT1

judge threshold 1

adjustment

The internally set judge threshold value 1 is output at

the VOUT pin.

0110 ADT2

judge threshold 2

adjustment

The internally set judge threshold value 2 is output at

the VOUT pin.

0111 AHY1 hysteresis voltage 1

The hysteresis voltage of the comparator 1 is output at

the VOUT pin.

1000 AHY2 hysteresis voltage 2

The hysteresis voltage of the comparator 2 is output at

the VOUT pin.

1001 ALV

Output reference

voltage adjustment

The output reference voltage is output at the VOUT

pin.
