(3) Priority specification flag registers (PR0L, PR0H, PR1L, PR1H)
R01UH0008EJ0401 Rev.4.01
Jul 15, 2010
Caution Be sure to set bits 2, 4 to 7 of PR1L and bits 1 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 signal generation sets these registers to FFH.
