Three standard 8051 Ports (0, 1, and 2) are available on the MCUs. The C8051F060/2/4/6 have 4 addi-
tional 8-bit ports (3, 5, 6, and 7), and a 3-bit port (port 4) for a total of 59 general-purpose I/O Pins. The
Ports behave like the standard 8051 with a few enhancements.
Each port pin can be configured as either a push-pull or open-drain output. Also, the "weak pull-ups" which
are normally fixed on an 8051 can be globally disabled, providing additional power saving capabilities for
low-power applications.
Perhaps the most unique enhancement is the Digital Crossbar. This is a large digital switching network that
allows mapping of internal digital system resources to Port I/O pins on P0, P1, P2, and P3.
(See Figure 1.9) Unlike microcontrollers with standard multiplexed digital I/O ports, all combinations of
functions are supported with all package options offered.
The on-chip counter/timers, serial buses, HW interrupts, comparator outputs, and other digital signals in
the controller can be configured to appear on the Port I/O pins specified in the Crossbar Control registers.
This allows the user to select the exact mix of general purpose Port I/O and digital resources needed for
the particular application.
