(3) Priority specification flag registers (PR0L, PR0H, PR1L, PR1H)
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.
