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. trim bits can be locked by a lock bit. Remark: OTP assignment will be defined/updated. Table 12. Serial Bit Sequence (16-bit read / write)
7.8 Analog Sin/Cos Outputs wi th External Interpolator

- We recommend to use a 100k pull-up resistance.
- Default conditions for unused pins are: DCLK, CS, DIO, TC, A_TST, TBO, TB1, TB2, TB3 connect to VSS
7.9 OTP Programming and Verification
Figure 9. OTP Programming Connection (special case setup), if the capacitors can not be removed at final assembly. Due to D1, the capacitors C1+C2 are loaded with VDD - 0.7V at startup, hence not influencing the readout of the internal OTP registers. During programming the OTP, the diode ensures that no current is flowing from PROG (8V - 8.5V) to VDD (5V). In the standard case (see Figure 9), the verification of a correct OTP readout can be done by analog readback of the OTP register. assembly, the special setup is recommended.
