If I read the programming specs of the 12F675,
(which by coincidence I'm doing right now ;-)
and see the schematic of the wisp628,
I don't understand how the wisp628 is able to program a 12F675 ....
... the 12F675 programming specs state ...
... to enter programming mode hold data+clock low, no Vdd,
... rise Vpp,
... wait >5usec
... rise Vdd
... wait >5usec
I don't see a switch in the Vdd line ???

cheers,
