C8051F2xx-DK
6.4. Analog I/O (J5, J6, J7, Terminal Block)
An Analog I/O Configuration connector (J6) provides the ability to route analog I/O signals from the C8051F2xx to
a terminal block in addition to connector J2 by installing shorting blocks on J6. Additionally, if shorting blocks are
installed on J5 and J7, the analog signals routed through J6 can be inputs to the C8051F2xx at port pins P3.0
and/or P3.1. The port pins can then be configured as inputs to the on-chip ADC for evaluation. J6 also allows the
user to route analog signals from the terminal block to port pins P1.3 and P1.4. These port pin can then be
configured as inputs to Comparator 1. The PWM signal from the low-pass filter is also routed to J6 to provide a
user controlled analog voltage level. This signal can then be used to evaluate the on-chip ADC by placing a
shorting block on J6 (provided the J5 or J7 header is shorted). Refer to Figure 3 to determine the shorting block
installation positions required to create the desired analog signal paths. Refer to Table 3 for terminal block
connections and Table 4 for J6 pin definitions.
