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.
