Bits 5 and 4—Interrupt Control Mode 1 and 0 (INTM1, INTM0): These bits select one of two interrupt control modes
for the interrupt controller.
Bit 3—NMI Edge Select (NMIEG): Selects the input edge for the NMI pin.
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 (levels 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: These bits cannot be modified and are always read as 0.
