Documentation of drive and limitations for STEVAL-ESC002V1 / STSPIN32F0A is missing

I have been going through the datasheets to find the capabilities of the bootstrap system in the STEVAL-ESC002V1 board and the STSPIN32F0A and can not find it.

How long can the system hold a motor phase high, and how long does the bootstrap hold a charge. This is important for motor initialization and drive frequency (pwm) limitations.

I am evaluating this chip for use in custom driver and currently it appears to struggle with keeping signals clean. Bootstrap failure is occuring quickly during initial position detection and startup. (Not using the supplied firmware as that is not very usefull. 0-cross detection and startup ramp is no good for fast startup.)
