Key events tracking in TCA8418

Other Parts Discussed in Thread: TCA8418

With reference to datasheet of TCA8418 ( SCPS215B –SEPTEMBER 2009–REVISED MARCH 2010) , i want to clarify the Key events tracking in TCA8418 for the following scenario

  • Press a key
  • Interrupt INT occurs (INT goes low ie ASSERTED)
  • Read the key event from the key event register
  • Clear the K_INT bit of the status register
  • Interrupt line INT goes HIGH(DEASSERTED)
  • Key remains still pressed
  1. In this case will another interrupt be triggered , signalling the "KEY PRESS" for the same key?
  2. Or will the interrupt occur only when some other key event occurs or the pressed key (in our case) is released?
