AM3356: Interrupt priority

g.f.

Part Number: AM3356

Hi,

I have a question about AM335x Interrupt.

In INTC_ILR_x(x=0 to 127)register bit[7:2],
the user can configure the priority of each interrupt.
From this register, we can set upto 63(lowest priority?).
But from TRM(spruh73q) page.532 "6.1.1.2.2 Priority Masking",
lowest priority is 0x7F(127).

How can we set the interrupt priority to 127 from INTC_ILR_x?
Or can the user set the priority only upto 63?

best regards,
g.f.

Hi g.f.,

The priority can only be set up to 63.

I have submitted a ticket to update section "6.1.1.2.2 Priority Masking" in the TRM.

Melissa
