8.4 Programming Verification
After programming, the programmed OTP bits may be verified in two ways:
- By digital verification:
this is simply done by sending a READ OTP command (#0F
commands.
- By analog verification:
By sending an ANALOG OTP READ command (#09
a sequence of the bits in the OTP register. A voltage of <500mV indicates a correctly programmed bit (“1”) while a voltage level between 2.2V
and 3.5V indicates a correctly unprogrammed bit (“0”). Any voltage level in between indicates improper programming.

8.5 AS5030 Status Indicators
Refer to
8.5.1 C2 Status Bit
This bit represents the hardware connection of the C2 configuration pin (#15) to determine, which hardware configuration is selected for the
AS5030 in question.
C2 = low: pin C2 is low, indicating that the AS5030 is in 3-wire mode or a member of a 2-wire daisy chain connection (except the last)
C2 = high: pin C2 is high, indicating that the AS5030 is in 2-wire mode and/or the last member of a 2-wire daisy chain connection
8.5.2 Lock Status Bit
The Lock signal indicates the ADC lock status. If Lock = low (ADC unlocked), the angle information is invalid.
To determine a valid angular signal at best performance, the following indicators should be set:
Lock = 1
AGC > 00
Note: The angle signal may also be valid (Lock = 1), when the AGC is out of range (00
