Mab

hi

In the Programming the SX Microcontroller Book program one debug stepping after I press step it goes to sleeping mode.

I am also getting a lot of Chip Connection Failed Errors.

rb,

Have you looked in this sticky on the front page of the forum to see things you might try?

Mab,

do you have a resonator or xtal attached to the OSC1 and OSC2 pins while you are trying to debug? A resistor (like 10 kOhm) between OSC1 and OSC2 may also cause such a problem.

Please let us know what the problem finally was - it may help others.

Was it the

MOV W, #FE

I assume, it should read

MOV W, #$FE

right ?
