help
The interrupt assignment registers controls the pin-to-interrupt
assignment in a byte-wide manner. Each option allows you to select
a set of pins (High/Low Byte) of an specific Port being mapped
to one of the four PIN Interrupts IRQ_PINTx.
You shouldn't change any of these unless you know exactly what you're doing.
Please consult the Blackfin BF54x Processor Hardware Reference Manual.
