MMPF0100 preprogrammed with VTT?

Why isn't VTT mode enabled on any of the pre-programmed OTP versions of the MMPF0100? That could make this PMIC far more convenient for i.MX 6 CPUs.

The typical usage scenario of the i.MX6 series processors implies the use of 4
DDR3 chips, located on both sides of the PCB and routed with T topology, that
does not require the VTT termination. That's why no pre-programmed MMPF0100
configuration, supporting the VTT feature, is provided. To implement the VTT
feature, a custom OTP configuration should be programmed to the NP version of
MMPF0100 at board production stage.


Have a great day,
Artur
