RESET CIRCUIT
To reset the microcomputer, RESET pin should be held at an “L”
level for 16 cycles or more of XIN. Then the RESET pin is
returned to an “H” level (the power source voltage should be
between 1.8 V and 5.5 V (between 2.7 V to 5.5 V for flash
memory version), and the oscillation should be stable), reset is
released. After the reset is completed, the program starts from the
address contained in address FFFD16 (high-order byte) and
address FFFC16 (low-order byte). Make sure that the reset input
voltage for the mask ROM version is less than 0.29 V for VCC of
1.8 V.
In the flash memory version, input to the RESET pin in the
following procedure.
When power source is stabilized
(1) Input “L” level to RESET pin.
(2) Input “L” level for 16 cycles or more to XIN pin.
(3) Input “H” level to RESET pin.
At power-on
(1) Input “L” level to RESET pin.
(2) Increase the power source voltage to 2.7 V.
(3) Wait for td(P-R) until internal power source has stabilized.
(4) Input “L” level for 16 cycles or more to XIN pin.
(5) Input “H” level to RESET pin.

Notes 1: The frequency relation of f(XIN) and f(
φ) is f(XIN) = 8 f(φ).
2: The question marks (?) indicate an undefined state that depends on the previous state.
