Reading through datasheet for D series (checking out and familiarizing ourselves with stuff) http://ww1.microchip.com/downloa... I've noticed the following:
High speed and low speed mode power consumption is specified for analog comparator only for 128D4 (page 126), the ATxmega64D4 has only high speed mode power consumption spelled out for AC on page 105, and the rest don't seem to have power consumption for AC stated at all.
Moreover, the D-manual http://ww1.microchip.com/downloa... does not mention HSMODE bit, and that bit is listed as RESERVED on page 257.
So, how should I interpret that?
Is HSMODE available on 128D4? Other D4 chips?
If not, in what mode is it operating and what approximate power consumption hit should one expect?
