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. After the reset is com-
pleted, 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
(switching to the high-speed mode, a power source voltage must be
between 4.0 V and 5.5 V).
