8.11 Reset
Reset of the PCA9665 to its default state can be performed in 2 different ways:
By holding the RESET pin LOW for a minimum of t
w(rst)
.
By using the Parallel Software Reset sequence as described in
Figure 18
.

through
Figure 22
) illustrate typical timing diagrams for the
PCA9665 in master/slave functions.
