6.4. Analog I/O (J6, Terminal Block)
An Analog I/O Configuration connector (J6) provides the ability to route analog I/O signals from the C8051F005
device to a terminal block by installing two shorting blocks on J6. It also allows the DAC outputs to be connected to
Comparator 0 inputs or to two ADC inputs. Analog signals may be routed to the AIO 0 and AI01 posts of the termi-
nal block by installing a shorting block between two adjacent pins on J6. Refer to Figure 3 to determine the shorting
block installation positions required to connect the desired analog signal to the terminal block. Refer to Table 3 for
terminal block connections and Table 4 for J6 pin definitions.
