These pins make up Port F. These port pins are configurable and can have the
following functions:
– MCU I/O – standard output or input port;
– External Chip Select (ECS0-ECS7) outputs, or inputs to CPLD;
– Latched address outputs;
– Address A1-A3 inputs in 80C51XA mode (PF0 is grounded);
– Data bus port (D0-D7) in a non-multiplexed bus configuration;
– Peripheral I/O mode; and
– MCU RESET mode.
