Description

R_EDIV

15:13

Bit [0:2] from EDIV Register (0x20/0x30)

OTPF

Occurs when signature of the OTP is wrong

PPSF

Pin-to-Pin short Error. Pins under test are shorted

together. Blanking not needed.

BPFF

Occurs when voltage of internal filter is exceeding the

operating range.

REGF

Error Flag (=1) occurs Regulator voltage is exceeding

the operating range. Blanking not needed.

OCSLD

Error Flag (=1) occurs when current exceeds the

maximum limit.

OCSEN

Error Flag (=1) occurs when current exceeds the

maximum limit.

TEST

For internal use

TX1F

Error Flag (=1) occurs output voltage of sensor driver is

exceeding the operating range.

TX2F

Error Flag (=1) occurs output voltage of VAR_SEN

driver is exceeding the operating range.

PGA1F

PGA1F=1 when I channel is saturated high or low.

PGA2F

PGA2F=1 when Q channel is saturated high or low.

NCLK

NCLK=1 when the clock is missing or invalid on CLK_E

CBF

CBF=1 occurs when output voltage of current buffer is

exceeding the operating range.

7.2.3

I-Channel Data (Address 0x03)

According to the register settings the Accumulated Data for the I-Channel. Dependent on the

accumulation setting in the ADCTL register (0x2A/0x3A), the value can be from 12 up to 14 bits.

The content of the register can be read out with command 0x90.
