Data Sheet
11.3 Non-permanent Programming
It is also possible to re-configure the AS5045 in a non-permanent way by overwriting the OTP register.
This procedure is essentially a “Write Data” sequence (see Figure 10) without a subsequent OTP programming
cycle.
The “Write Data” sequence may be applied at any time during normal operation. This configuration remains set while
the power supply voltage is above the power-on reset level (see 6.6).
See Application Note AN5000-20 for further information.
