10. Interrupt Controller (INTC)
(3)
INTPRI is a 32-bit readable/writable register used to set the priorities of IRQ[7:0] (as levels from
15 to 0). These settings are only valid for IRQ/IRL7 to IRQ/IRL4 or IRQ/IRL3 to IRQ/IRL0 when
set up as individual IRQ interrupts (IRQ7 to IRQ0 interrupts) by setting the IRLM0 or IRLM1 bit
in ICR0 to 1.
Note: Interrupt priorities are established by setting values from H'F to H'1 in each of the 4-bit
