HMC5883L
Mode Register
The mode register is an 8-bit register from which data can be read or to which data can be written. This register is used to
select the operating mode of the device. MR0 through MR7 indicate bit locations, with MR denoting the bits that are in the
mode register. MR7 denotes the first bit of the data stream. The number in parenthesis indicates the default value of that
bit.

Operating Mode
Continuous-Measurement Mode. In continuous-measurement mode,
the device continuously performs measurements and places the
result in the data register. RDY goes high when new data is placed
in all three registers. After a power-on or a write to the mode or
configuration register, the first measurement set is available from all
three data output registers after a period of 2/f
measurements are available at a frequency of f
frequency of data output.
Single-Measurement Mode (Default). When single-measurement
mode is selected, device performs a single measurement, sets RDY
high and returned to idle mode. Mode register returns to idle mode
bit values. The measurement remains in the data output register and
RDY remains high until the data output register is read or another
measurement is performed.
Idle Mode. Device is placed in idle mode.
Idle Mode. Device is placed in idle mode.

Description
These bits must be cleared for correct operation. Bit MR7
bit is set internally after each single-measurement
operation.
Mode Select Bits. These bits select the operation mode of
this device.
