CHAPTER 19 INTERRUPT FUNCTIONS
(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).
PR00L, PR00H, PR01L, PR01H, PR02L, PR02H, PR10L, PR10H, PR11L, PR11H, PR12L, and PR12H can be set by
a 1-bit or 8-bit memory manipulation instruction. If PR00L and PR00H, PR01L and PR01H, PR02L and PR02H,
PR10L and PR10H, PR11L and PR11H, and PR12L and PR12H 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.
