I'm using an AT89S52 microcontroller, and when I hooked the power up, the chip did respond to key presses, however, when I issued a reset (shorted the 2.2uF capacitor between reset pin and VCC), the results appeared to be stalled, and the micrcontroller ignored button presses, and the only way to get it to respond is to remove the power, wait a few minutes and re-apply power.
I checked the manual and it talks about watchdog timer and idle/power down mode, but I never enabled those modes, but I did however initialize all the variables at the beginning of my program. Is there anything I can do to fix this? (like is there anything I can do to force watchdog and power down mode or idle mode to be disabled?)
