(3) Priority specification flag registers (PR0L, PR0H, PR1L)
Address: FFE8H After reset: FFH R/W
Symbol
PR0L
Address: FFE9H After reset: FFH R/W

PR0H
Address: FFEAH After reset: FFH R/W
Symbol
PR1L
Cautions 1. If the watchdog timer is used in watchdog timer mode 1, set the WDTPR flag to 1.
The priority specification flags are used to set the corresponding maskable interrupt priority orders.
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 by a 16-bit memory manipulation instruction.
RESET input sets these registers to FFH.
Notes 1. Incorporated only in the PD780024AY, 780034AY Subseries. Be sure to set 1 for the PD780024A,
2. Incorporated only in the PD780024A, 780034A Subseries. Be sure to set 1 for the PD780024AY,
