EXT IRQ driver
|
|
==============
|
|
|
|
The External Interrupt driver allows external pins to be
|
|
configured as interrupt lines. Each interrupt line can be
|
|
individually masked and can generate an interrupt on rising,
|
|
falling or both edges, or on high or low levels. Some of
|
|
external pin can also be configured to wake up the device
|
|
from sleep modes where all clocks have been disabled.
|
|
External pins can also generate an event.
