Digital/Analog Configurable I/O
The standard 8051 Ports (0, 1, 2, and 3) are available on the device. The ports behave like standard 8051
ports with a few enhancements.
Each port pin can be configured as either a push-pull or open-drain output. Any input that is configured as
an analog input will have its corresponding weak pull-up turned off.
Digital resources (timers, SPI, UART, system clock, and comparators) are routed to corresponding I/O pins
by configuring the port multiplexer. Port multiplexers are programmed by setting bits in SFR's (please see
Section 14). Any of the 32 external port pins may be configured as either analog inputs or digital I/O (See
Figure 1.9), so effectively, all port pins are dual function.
