ImgTec Powerdown Controller (PDC) Interrupt Controller has a number of input
|
|
interrupt lines which can wake the system, and are passed on through output
|
|
interrupt lines.

flags as follows (only 4 valid for peripheral interrupts):
|
|
0 = none (decided by software)

1 = low-to-high edge triggered
