5.2.2
The IPR registers are eleven 8-bit readable/writable registers that set priorities (levels 7 to 0) for
interrupts other than NMI.
The correspondence between IPR settings and interrupt sources is shown in table 5.3.
The IPR registers set a priority (level 7 to 0) for each interrupt source other than NMI.
The IPR registers are initialized to H'77 by a reset and in hardware standby mode.
Bits 7 and 3—Reserved: Read-only bits, always read as 0.
