I know!  Why the heck would anyone want to do that?!?  But, what if you wanted two brightness levels--levels that extended beyond the dynamic range of the "256-Step Programmable Global Current Gain" feature?

Well, you might switch Rext in and out of circuit.  The datasheet seems to imply that both states are sanctioned: Tables 7.5 and 7.6 include an IDD case where Rext = "Open"

So, is running the TLC5916/17 device without an Rext connected, in fact, an approved mode?
