1) Connect either one end of the oscillatory capacitors C
G
and C
D
to the VDD pin.
2) Install the by-pass capacitors for both high and low fre-
quencies in close proximity to the IC in such a manner
as to form a parallel arrangement.
3) Connect the pull-up resistor of the INTR pin to differ-
ent points depending on whether it is used while the
CE pin is held low (in battery backup).
(I) Connect the pull-up resistor to Point A in the left
circuit diagram unless it is used while the CE pin
is held low.
(II) Connect the pull-up resistor to Point B in the left
circuit diagram if it is used while the CE pin is
held low.
