Note:
1) The resolution on the digital serial interface is always 12bit (0.088°/step) over 360°, independent of analog mode
15.3 Repeated OTP Programming
Although a single AS5046 OTP register bit can be programmed only once (from 0 to 1), it is possible to program
other, unprogrammed bits in subsequent programming cycles. However, a bit that has already been programmed
should not be programmed twice. Therefore it is recommended that bits that are already programmed are set to “0”
during a programming cycle.
15.4 Non-permanent Programming
It is also possible to re-configure the AS5046 in a non-permanent way by overwriting the OTP register.
This procedure is essentially a “Write Data” sequence (see Figure 13) 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 7.5).
See Application Note AN5000-20 for further information.
