• Manufacturer: Renesas Electronics Corporation.

(3) Priority specification flag registers (PR0L, PR0H, PR1L)
The priority specification flag registers are used to set the corresponding maskable interrupt priority order.
PR0L, PR0H, and PR1L are set by a 1-bit or 8-bit memory manipulation instruction. If PR0L and PR0H are
combined to form 16-bit register PR0, they are set with a 16-bit memory manipulation instruction.
RESET input sets these registers to FFH.
Notes 1.
Caution Be sure to set bits 2 to 7 of PR1L to 1.
