I´m trying to get running jm 60 but  I don´t  work.
I do I simple program  to turn on and off a led , for test the mcu.
then I burn the program using bdm.
Until here, there is no problem with anything.
But when I want to see if it works, it don´t do anything.
I have burn diferents programs but nothing happens, I think the problem is in my hardaware.
I used:
xtal = 12Mhz
Rf = 1M
all vdd = 5V
all Vss =ground.
I can´t see where is the problem or why the program no runs.
I do the connections  that suggest in datasheet.
as the attach.
Thanks for your help.
