16.3.12. SetOTPParam
This command is provided to the circuit by the I
Important: This command must be sent under a specific Vbb voltage value. See parameter VbbOTP in Table 5. This is a mandatory
condition to ensure reliable zapping.
16.3.13. SetPosition
This command is provided to the circuit by the I
details. The priority encoder table
16.3.14. SoftStop
This command will be internally triggered when the chip temperature rises above the thermal shutdown threshold (see Table 5 and
Section 14.2.5). It provokes an immediate deceleration to Vmin (see
reached. Once the motor is stopped, TagPos register is overwritten with value in ActPos register to ensure keeping the stop position.
The I
16.3.15. TestBemf
This command is provided to the circuit by the I
Once activated, it can be stopped only after POR. During the Bemf observation, reading of the SWI state is internally forbidden.
SetOTPParam corresponds to the following I
SetPosition corresponds to the following I
SoftStop corresponds to the following I
2
C Master for some safety reasons can also issue a SoftStop command.
