Target Category: Delfino, F280x, Piccolo
The GPIO Qualification block lets you choose the qualification time interval for GPIO pins on the supported devices. Selection of qualification can help filter noise and remove glitching from external signals.
Before you configure the GPIO pins, it is a good idea to first insert a corresponding target configuraton block in your diagram and specify the CPU device.
GPIO Bank: Selects the bank of GPIO pins to configure. The default is GPIO Bank 0.
GPIO0-x: Selects synchronization or qualification duration for a given GPIO input pin and is updated in the GPIO Input dialog. This is used for filtering out noise. You can sample at 3 or 6 clock ticks or choose No Sync or Qualification, which means it is not synchronized to any internal clock. The default is Sync to SYSCLKOUT.
Qualification Period: Selects the duration of a qualification sample. The default is SYSCLKOUT/1.
