5.3.1
The IPR registers are fourteen 8-bit readable/writable registers that set priorities (levels 7 to 0) for
interrupts other than NMI. The correspondence between interrupt sources and IPR settings is
shown in section 5.4.3, Interrupt Exception Handling Vector Table. Setting a value in the range
from H'0 to H'7 in the 3-bit groups of bits 6 to 4 and 2 to 0 sets the priority of the corresponding
interrupt.
