RESET CIRCUIT
To reset the microcomputer, RESET pin must be held at an “L”
level for 20 XIN cycles or more. Then the RESET pin is returned to
an “H” level (the power source voltage must be between 2.7 V and
3.6 V, and the oscillation must be stable), reset is released. After
the reset is completed, the program starts from the address con-
tained in address FFFD16 (high-order byte) and address FFFC16
(low-order byte). Make sure that the reset input voltage is less
than 0.54 V for VCC of 2.7 V.

1: The frequency relation of f(XIN) and f(
φ) is f(XIN) = 2 f(φ).
2: The question marks (?) indicate an undefined state that depends on the previous state.
3: All signals except XIN and RESET are internals.
Reset address from the vector table.
