(3) Priority specification flag registers (PR0L, PR0H, PR1L, PR1H)
Note
Caution Be sure to set bits 5 to 7 of PR1H to 1.
The priority specification flag registers are used to set the corresponding maskable interrupt priority order.
PR0L, PR0H, PR1L, and PR1H are set by a 1-bit or 8-bit memory manipulation instruction. If PR0L and PR0H,
and PR1L and PR1H are combined to form 16-bit registers PR0 and PR1, they are set by a 16-bit memory
manipulation instruction.
RESET input sets these registers to FFH.
