Magnetic data-ready status register.

This register indicates the real-time status information of the X, Y, and Z magnetic sample data.

zyxow

zyxow is set to one whenever new magnetic data is acquired before completing the retrieval of the previous data set. This 
event occurs when the content of at least one magnetometer output data register (that is, M_OUT_X/Y/Z) has been 
overwritten. zyxow is cleared when the most significant bytes of the magnetometer data (M_OUT_X_MSB, M_OUT_Y_MSB, 
and M_OUT_Z_MSB) are read.
X, Y, Z-axis data overwrite:
0: No data overwrite has occurred 
1: Previous X-, Y-, Z-magnetic data was overwritten by new X, Y, Z data before it was completely read

zow

zow is set to 1 whenever a new Z-axis acquisition is completed before the retrieval of the previous data. When this occurs 
the previous data is overwritten. zow is cleared anytime the M_OUT_Z_MSB register is read.
Z-axis data overwrite:
0: No data overwrite has occurred 
1: Previous Z-axis magnetic data was overwritten by new Z-axis data before it was read

yow

yow is set to 1 whenever a new Y-axis acquisition is completed before the retrieval of the previous data. When this occurs 
the previous data is overwritten. yow is cleared anytime M_OUT_Y_MSB register is read.
Y-axis data overwrite:
0: No data overwrite has occurred 
1: Previous Y-axis magnetic data was overwritten by new Y-axis data before it was read

xow

xow is set to 1 whenever a new X-axis acquisition is completed before the retrieval of the previous data. When this occurs 
the previous data is overwritten. xow is cleared anytime the M_OUT_X_MSB register is read.
X-axis data overwrite:
0: No data overwrite has occurred
1: Previous X-axis magnetic data was overwritten by new X-axis data before it was read

zyxdr

zyxdr signals that a new acquisition for the X, Y, and Z axes magnetic data is available. zyxdr is cleared when the most 
significant bytes of the magnetometer data (M_OUT_X_MSB, M_OUT_Y_MSB, and M_OUT_Z_MSB) are read.
X, Y, Z new data available:
0: No new set of X, Y, Z magnetic data is available
1: A new set of X, Y, Z magnetic data is available

zdr

zdr is set to 1 whenever a new Z-axis data acquisition is completed. zdr is cleared anytime the M_OUT_Z_MSB register is 
read. Z-axis new data available:
0: No new Z-axis magnetic data is available
1: New Z-axis magnetic data is available

ydr

ydr is set to 1 whenever a new Y-axis data acquisition is completed. ydr is cleared anytime the M_OUT_Y_MSB register is 
read. Y-axis new data available:
0: No new Y-axis magnetic data is available
1: New Y-axis magnetic data is available

xdr

xdr is set to 1 whenever a new X-axis data acquisition is completed. xdr is cleared anytime the M_OUT_X_MSB register is 
read. X-axis new data available:
0: No new X-axis magnetic data is available.
1: New X-axis magnetic data is available
