Output Port (R00, R01)
The E0C6001 Series have a 2-bit general output port (R00,
R01).
Output specification of the output port can be selected in a
bit unit with the mask option. Two kinds of output specifi-
cations are available: complementary output and Pch open
drain output. Also, the mask option enables the output
ports R00 and R01 to be used as special output ports.
Figure 4.4.1 shows the configuration of the output port.
