How can I set the interrupt priority for each IRQ ID#?
The registers ICDIPR0 - 23 are found in TRM but there is no detail.
ICDIPRx registers consist of four 8bit fields.
Each field is associated with each IRQ ID#0 - 95.
ICDIPR0 Byte0([7:0]) - IRQ ID#0,
ICDIPR0 Byte1([15:8]) - IRQ ID#2,
ICDIPR0 Byte3([23:16]) - IRQ ID#3,
For more detail, refer to the ARM Document below:
