Notice: This is not a final specification.
Some parametric limits are subject to change.
Fig 57. 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.
