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 2.5 V and
5.5 V, and the oscillation should be stable), reset is released. In or-
der to give the XIN clock time to stabilize, internal operation does
not begin until after 8200 XIN clock cycles (timer 1 and timer 2 are
connected together and 512 cycles of f(XIN)/16) are complete. Af-
ter 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 is less than 0.5 V for VCC of
2.5 V (Extended operating temperature version: the reset input
voltage is less than 0.6V for VCC of 3.0V).
