RESET CIRCUIT
To reset the microcomputer, RESET pin should be held at an “L”
level for 2 s or more. Then the RESET pin is returned to an “H”
level (the power source voltage should be between VCC(min.) and
5.5 V, and the quartz-crystal oscillator 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 ad-
dress FFFC16 (low-order byte). Make sure that the reset input
voltage meets VIL spec. when a power source voltage passes
VCC(min.).

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