[STSPIN32F0] 6-step control: Set phase out in float mode

Hello,

I am using the STEVAL-SPIN3201 board to control a BLDC motor.

I want to implement a position controller, so I need to hold tight the position of the rotor at a given position (1 phase to Gnd, 1 phase to pulsed Vm, and 1 floating phase).

The problem that I am encountering now, is that the Control logic gate driver embedded inside the STSPIN32F0 does not allow to set both High and Low n-channel mosfet gates at the same position (1 & 1 or 0 & 0). I understand that 1 & 1 causes a short-circuit , but I need 0 & 0 in order to set the floating phase.

Is it possible to set a floating phase on STSPIN32F0?

Thank you in advance.
