Operational Mode Registers
EEPROM registers 0x04 and 0x05 contain bits that are read for operational mode status and for setting the Run Mode
measurement rate. The tables below describe the register contents and interpretation. It is recommended that Operational
Mode Register 1 and 2 written only to change default orientation and update measurement rate.

User Hard-Iron Calibration
The HMC6343 provides a user calibration routine with the 0x71 command permitting entry into the calibration mode and
the 0x7E command to exit the calibration mode.
After entering the calibration mode, rotate the device reasonably steady for 360 degrees about the Y (Left - Right) axis
and then 360 degrees about Z (Up - Down) axis. During the first rotation, maintain the Y axis at Level as much as
possible. Maintain the Z axis upright as much as possible during the second rotation and until the exit calibration
