RL78/G1A CHAPTER 16 INTERRUPT FUNCTIONS
16.3.3 Priority specification flag registers (PR00L, PR00H, PR01L, PR01H, PR02L, PR02H, PR10L, PR10H, PR11L,
PR11H, PR12L, PR12H)
The priority specification flag registers are used to set the corresponding maskable interrupt priority level.
A priority level is set by using the PR0xy and PR1xy registers in combination (xy = 0L, 0H, 1L, 1H, 2L, or 2H).
The PR00L, PR00H, PR01L, PR01H, PR02L, PR02H, PR10L, PR10H, PR11L, PR11H, PR12L, and the PR12H
registers can be set by a 1-bit or 8-bit memory manipulation instruction. If the PR00L and PR00H registers, the PR01L
and PR01H registers, the PR02L and PR02H registers, the PR10L and PR10H registers, the PR11L and PR11H registers,
and the PR12L and PR12H registers are combined to form 16-bit registers PR00, PR01, PR02, PR10, PR11, and PR12,
they can be set by a 16-bit memory manipulation instruction.
Reset signal generation sets these registers to FFH.
Remark If an instruction that writes data to this register is executed, the number of instruction execution clocks
increases by 2 clocks.
