Datasheet - Detailed Description
7.6 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.
Figure 7. Digital Interface at Analog Readback of Zener Diodes
7.7 One Time Programming Content
The AS5115 die has an integrated 46-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.
As shown in the table below, the OTP holds 46 bits. Bit number 44 and 45 are used for OTP testing purposes and ESD protection of the
remaining cells.
Remark: OTP assignment will be defined/updated.
