AS5043 Programmable 360° Magnetic Angle Encoder
Integral Non-Linearity (INL) is the maximum deviation between actual position and indicated position.
Differential Non-Linearity (DNL) is the maximum deviation of the step length from one position to the next.
Transition Noise (TN) is the repeatability of an indicated position.

Note
Time between falling edge of CSn and data output activated
Time between falling edge of CSn and first falling edge of
CLK
Rising edge of CLK shifts out one bit at a time
Time between rising edge of CLK and data output valid
After the last bit DO changes back to “tristate”
CSn = high; To initiate read-out of next angular position
