PRELIMINARY

Notice: This is not a final specification.

Some parametric limits are subject to change.

Fig 56. Timing diagram at reset

Notes 1: X : Undefined

2: The content of other registers is undefined when the microcomputer is reset.

The initial values must be surely set before you use it.

3: Do not access to the SFR area including nothing.

4: When the setting by the function set ROM data 2 (FSROM2) is performed,

the initial values of this bit at reset are changed.
