Edge Port Module (EPORT)
15.1
The edge port module (EPORT) has seven external interrupt pins, IRQ7–IRQ1. Each pin can be
configured individually as a level-sensitive interrupt pin, an edge-detecting interrupt pin (rising
edge, falling edge, or both), or a general-purpose input/output (I/O) pin. See
15.2
This section describes the operation of the EPORT module in low-power modes. For more
information on low-power modes, see
EPORT module operation in low-power modes, and describes how this module may exit from each
mode.
