RESET CIRCUIT
To reset the microcomputer, RESET pin should be held at an “L”
level for 2
μ
s or more. Then the RESET pin is returned to an “H”
level (the power source voltage should be between 3.0 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 FFFD
16
(high-order byte) and address FFFC
16
(low-
order byte). Make sure that the reset input voltage is 0.6 V or less
for V
CC
of 3.0 V.
