12.3 Repeated OTP Programming
Although a single AS5043 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.
12.4 Non-permanent Programming
It is also possible to re-configure the AS5043 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 19.5).
See Application Note AN5000-20 for further information.
12.5 Digital-to-Analog Converter (DAC)
The DAC has a resolution of 10bit (1024 steps) and can be configured for the following options.
