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 2.8 V and 5.5
V, and X
IN
oscillation is stable), reset is released. In order to give
the X
IN
clock time to stabilize, internal operation does not begin
until after about 4000 X
IN
clock cycles (256 cycles of f(X
IN
)/16) are
completed. After the reset is completed, the program starts from
the address contained in address FFFD
16
(high-order) and ad-
dress FFFC
16
(low-order). Make sure that the reset input voltage
is 0.5 V or less for 2.8 V of V
CC
.
