Hi,
 

A have written an interrupt routine in SX/B for blinking a LED in different ways (50% duty cycle or selectable LED on/off time) I will be a part of an IR gate program.

This program is working fine on SX28. I can place WATCH-s  for the variablesin the program and can see them in debug mode.

I can start, stop, reset, etc the program in debug mode. (Is is working good.)

Programming this code into the chip the LED are blinking as I wanted. (using 4MHz internal osc.)

But!!! When I tried to use this code on SX48 os SX52 I run into strange problem. In debug mode I can only reset the program is is continously running. I can't stop it. (The stp button is not selectable.) I can not the WATCH changes.

I programmed the code into the chip, but the LED was not blinking as I wanted. (It seems that the interupt is not working.)

I tried other not interrup codes(PORT I/O and TIMER) on the SX48 and SX52 chips they was working, but the debug mode was working in the same way as with the interrupt routine.

I should tell that these chips are very old, as I remeber I got them as an engineering sample in 1998 or 1999. Can be this chips interrup and debug handling are not complette? Sould I by new ones? What Your suggestion?
