Output Ports (R00–R03, R10–R12)
The S1C62N82 Series have 7 bits for general output ports
(R00–R03 and R10–R12).
Output specifications of the output ports can be selected
individually with the mask option. Two kinds of output
specifications are available: complementary output, and Pch
open drain output. Also, the mask option enables the
output ports R10 and R12 to be used as special output
ports. Figure 4.4.1 shows the configuration of the output
ports.
