Cautions 1. If a watchdog timer is used in watchdog timer mode 1, set TMPR4 flag to 1.
2. Set always 1 in PR1L bits 3 to 7.
(3) Priority specify flag registers (PR0L, PR0H, and PR1L)
The priority specify flag is used to set the corresponding maskable interrupt priority orders.
PR0L, PR0H, and PR1L 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.
