(3) Priority specification flag registers (PR0L, PR0H)
The priority specification flags are used to set the corresponding maskable interrupt priority orders.
PR0L and PR0H are set with a 1-bit or 8-bit memory manipulation instruction. If PR0L and PR0H are used
as a 16-bit register PR0, use a 16-bit memory manipulation instruction for the setting.
Reset input sets these registers to FFH.
