3.2 Digital Inputs/Outputs
3.2.1 Digital Inputs
The Jackrabbit has six CMOS-level digital inputs, PB0–PB5, each of which is pulled up to
+5 V as shown in Figure 5. The BL1820, which does not have RS-485, has one additional
CMOS-level digital input, PC1.
Figure 5. Digital Inputs
The actual switching threshold is approximately 2.40 V. Anything below this value is a
logic 0, and anything above is a logic 1.
NOTE: Since the voltage limits on the inputs to the Rabbit 2000 microprocessor are 0 to
5.5 V DC, the end user must ensure that the voltage applied to any I/O pin is within
these limits.
