MOSI: SPI Master Output Slave Input line
When SPI is in master mode, MOSI outputs data to the slave peripheral.
When SPI is in slave mode, MOSI receives data from the master
controller.

I/O
Port 2: Port 2 is an 8-bit bidirectional I/O port with internal pull-ups. Port 2
pins that have 1s written to them are pulled high by the internal pull-ups
and can be used as inputs. As inputs, Port 2 pins that are externally
pulled low will source current because of the internal pull-ups. Port 2
emits the high-order address byte during fetches from external program
memory and during accesses to external data memory that use 16-bit
addresses (MOVX @DPTR).In this application, it uses strong internal
pull-ups emitting 1s. During accesses to external data memory that use
8-bit addresses (MOVX @Ri), port 2 emits the contents of the P2 SFR.

Port 3: Port 3 is an 8-bit bidirectional I/O port with internal pull-ups. Port 3
pins that have 1s written to them are pulled high by the internal pull-ups
and can be used as inputs. As inputs, Port 3 pins that are externally
pulled low will source current because of the internal pull-ups. Port 3 also
serves the special features of the 80C51 family, as listed below.

Reset: A high on this pin for two machine cycles while the oscillator is
running, resets the device. An internal diffused resistor to VSS permits a
power-on reset using only an external capacitor to V
CC. This pin is an
output when the hardware watchdog forces a system reset.
