(7544) Ports P00-P07 to input mode; key-on wakeup on for input P00

Latest Updated:03/01/2005

Question:

(Interrupts) Can ports P00 to P07 be set to input mode and key-on wakeup enabled only for input to P00? [2005/03/01]

Answer:

No.
Setting ports P00 to P07 to input mode enables key-on wakeup. However, bit 7 in the interrupt edge selection register (003Ah) can disable P00 individually. If P01 to P07 are set to input mode, their key-on wakeup functions are enabled. (#104951)
