• Priority, byte offset 3
• Priority, byte offset 2
• Priority, byte offset 1
• Priority, byte offset 0
Each priority field holds a priority value, 0-15. The lower the value, the greater the priority of the corresponding interrupt.
The processor implements only bits[7:4] of each field, bits[3:0] read as zero and ignore writes.
See
