Hello?
Is there a different group for the TS-7800; there seems to be alot of 7200 &
7400 questions?
I've attempted to contact TS for the past few days about this issue to no
avail. Just wondering if anyone has had similar experience and possibly a work
around for interrupt driven wake-up for TS-7800
I'm now looking into the ATMEGA48V AVR_RESET# (PC6) signal; or possibly some io
driven relay controlling the pwr directly...
Unfortunate when the documentation says it supports such a feature :[
thanks
