Voltage Regulator Status
This bit is a logical OR combination of Digital, Analog, GMR and
VDD_OV Comparator and GND_OFF, and VDD_OFF Comparator
outputs.
0: Voltage Supply OK
1: Voltage Supply is not OK
GMR_OFF

RU
ADC Values are no GMR values
(e.g.: Temperature measurement is active)
This bit indicates whether or not GMR values or any other values are
connected to the ADCs. This value is read back from the multiplexer
control signals.
0: X,Y Values are GMR values
1: X,Y Values normally represent temperature measurement or angle
test values. In the case of non-functional MUX, this bit is set to 1
UPDATE

RU
Update Toggle bit. This bit toggles after every update (update command
or automatic update at angle test)
The bit is independent of UR bit in CTRL1

Frame Counter (4-bit unsigned integer value)
This counter counts every new X,Y value pair coming out of the data
path. (approx. 80µs)
This counter is reset to 0_H after any write to FSYNC and after every
change of the ANGT_EN bit. As t_settle time has to elapse for valid X,Y
data, this counter must be ≥ 2_H to indicate valid X,Y values. If it
overflows, it resets to 3_H to show that values are still valid.
Note: If FIR_BYP is activated, this counter counts four times faster!
