8.6 Waveform – Digital Interface at Analog Readback of the Zener Diodes
To be sure that all Zener-Diodes are correctly burned, an analog readback mechanism is defined. Perform the ‘READ OTP ANA’ sequence
according to the command table and measure the value of the diode at the end of each phase.

Table 12. Serial Bit Sequence (16-bit read / write)
8.7 EasyZapp OTP Content
Each AS5215 die has an integrated 32-bit OTP ROM (Easyzapp) for trimming and configuration purposes. The PROM can be programmed via.
the serial interface. For irreversible programming, an external programming voltage at PROG pin is needed. For security reasons, the factory
trim bits can be locked by a lock bit.
Remark: OTP assignment will be defined/updated.
