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 2.7 V and 5.5 V, 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 is less than 0.5 V for VCC of 2.7 V
(switching to the high-speed mode, a power source voltage must be
between 4.0 V and 5.5 V).
