Description

7:0

PTAES[7:0]

Port A Edge Selects — Each of the PTAESn bits serves a dual purpose by selecting the polarity of the active

interrupt edge as well as selecting a pull-up or pull-down device if enabled.

0 A pull-up device is connected to the associated pin and detects falling edge/low level for interrupt generation.

1 A pull-down device is connected to the associated pin and detects rising edge/high level for interrupt

generation.
