| Aug 17, 2019 at 14:20 | comment | added | bobflux | @user3411864 apparently Toff is controlled by a DAC and the 3.2µs value corresponds to the maximum DAC value of 255, so that's the maximum Toff, not the minimum... but maybe it can also be adjusted by a resistor somewhere, I didn't read everything. | |
