The OTP tab
The OTP tab is normally used for the AS5000 programmer, but the OTP bits can be changed on the AS5x45 demoboard as
well.
Options like Zero Position, Pulses per revolution and Incremental Mode Selection can be changed by selecting the function
in "Fields", then changing the parameter in "Options for the selected field" or directly the decimal value of this parameter in
"Value".
Each time a field's value has been changed, the corresponding OTP bits will be automatically checked in the right window.
The button Write should be clicked to write the parameter into the AS5x45.
The Read button reads back the OTP register, and updates the "Field" parameter as well as the OTP bits window.
Figure 6: OTP tab
Field Zero Position: To zero position value, like on the SSI tab. The zero position value can be changed by checking the
Z[11:0] bits, or changing the Value field with a decimal number.
Note: The Zap! button is used for the AS5000 Programmer only and has no effect on the AS5x45 Demoboard.
