7.8. Port I/O Connectors (J1-J3 and J5-J7)
Each of the parallel ports of the C8051F540 (Side A) and C8051F542 (Side B) has its own 10-pin header
connector. Each connector provides a pin for the corresponding port pins 0–7, +5 V VIO, and digital ground. The
same pin-out is used for all of the port connectors.
Port 2 on the C8051F542 (Side B) MCU has only two pins and has a reduced header.
7.9. Voltage Reference (VREF) Connectors (J13 and J19)
The VREF connectors can be used to connect the VREF pin from the MCU (P0.0) to external 0.1 µF and 4.7 µF
decoupling capacitors. The C8051F540 (Side A) device is connected to the capacitors through the J13 header and
the C8051F542 (Side B) device connects to its own set of capacitors through J19.
7.10. Potentiometer (J17)
The C8051F540 (Side A) device has the option to connect port pin P1.2 to a 10K linear potentiometer. The
potentiometer is connected through the J17 header. The potentiometer can be used for testing the analog-to-digital
(ADC) converter of the MCU.
