Notes 1.
The reset value of WDTE is determined by setting of option byte.
2.
The value of this register is 00H immediately after a reset release but automatically changes to 80H after
oscillation accuracy stabilization of high-speed internal oscillator has been waited.
3.
The reset value of RESF vary depending on the reset source.
