Yes, it does read 50mA.

not further criticizing Bill's article, I'm curious about the PGA
performance.

The "PGA Specifications" table in the preliminary technical data is at
least confusing. I assume they mean 4LSB linearity error at higher
gains, else the whole PGA were useless.

But there is no indication about offset and noise. One ADC step at
full gain is just 32uV (3V / 4096 / 32 is 23uV).

It would be _great_, if these devices really contained a good PGA,
since a good external PGA costs as much as a whole 56F800x.

Any other microcontroller with a useful PGA?

and their 32KHz Osc figures are not great at all, looks like a design
oops there....

Also the table lacks any 1uA entry at all.. ?

Ummm, isn't that 50 ***mA***?  Not quite as impressive...

Standby currents of less than 1uA. Draws 50uA @ 32MHz.

These are new members of the Freescale MC56F800 Digital Signal Controller (DSC) family.

Article includes a roadmap and a chart of the low power modes.
