am interfacing a 4x3 matrix keypad with a PIC through the keypad encoder MM74C922. The problem I have is that some keys, when pressed multiple times, would give me different values, and there also seems to be a bouncing issue. I have put a 10uF capacitor across the osc pin and 100uF capacitor across the keybounce mask pin on the encoder. I have no idea why this is happening.
thank you.
attached the schematic.
