STAT_VR

Voltage Regulator Status

This bit is a logical OR combination of Digital, Analog,

GMR and VDDOV Comparator and GNDOFF, and

VDDOFF Comparator outputs.

0: Voltage Supply ok

1: Voltage Supply not ok

GMR_OFF

ADC Values are no GMR values

(e.g.: Temperature measurement is active)

This bit indicates, whether 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 temp. measurement

or angle test values. In case of non functional MUX this

bit is set to “1”

UPDATE

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

FCNT

3-0

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 0H after any write to FSYNC and

after every change of the ANGT_EN bit. As

tsettle time

has to be waited for valid X,Y data, this counter must be

≥ 2

H to indicate valid X,Y values. If it overflows, it resets

to 3H to show, that values are still valid.

Note: If FIR_BYP is activated, this counter counts 4

times faster!
