This is one of those super-secret automotive chips where almost no information
is available to the public. I'll need authoritative confirmation that all the
various parameters (b. m, output voltage format, minimum and maximum output
voltage, step size) match mpq7932 exactly. That is rarely the case, so consider
me skeptic.
