if I am not mistaken with "KBPATN = 0x22" the int will be activated only if both pins go high (p0.1 and p0.5)
You are mistaken "The Keypad Interrupt function is intended primarily to allow a single interrupt to be generated when Port 0 is equal to or not equal to a certain pattern." Thus if KBPATN 0x22 KBMASK = 0x22 KBCON = 2 0x22 int 0x00 no int 0x02 no int 0x20 no int Thus if KBPATN 0x22 KBMASK = 0x00 KBCON = 0 0x22 int 0x00 no int 0x02 int 0x20 int use what works and just ignore what you do not want in the ISR Erik |
