; Enables watchdog timer operation (illegal access detection operation),
; Window open period of watchdog timer: 50%,
; Overflow time of watchdog timer: 2
; Internal low-speed oscillator can be stopped by software.
; LVI default start function stopped
; Internal high-speed oscillation clock frequency 8 MHz (TYP.)
; Internal high-speed oscillator operation continues after execution of the STOP
; instruction in on-chip debug mode,
; Use the TOOLC0/X1, TOOLD0/X2 pins
; Shifting to on-chip debug mode after reset release
; Operation enabled. Does not erase data of the flash memory in case
; authentication of the on-chip debug security ID fails.
