Individual digital input channels may be also used for counters, synching, interrupts, input
capture, or as quadrature decoder inputs. The use of these channels for interrupts, input
capture, and as quadrature decoders is described below.
Blocks of digital input pins are associated with counters/timers on the Rabbit RIO chip.
Table 3 provides complete details for these associations.
Appendix D provides further details on the blocks and pins associated with the Rabbit
RIO chip to facilitate configuring each block consistently and to identify misconfigured
pins when a software function call returns a Mode Conflict error code.
BL4S100 User’s Manual
The actual switching threshold is approximately
1.40 V. Anything below this value is a logic 0,
and anything above 1.90 V is a logic 1. The
digital inputs are each fully protected over a
range of -36 V to +36 V, and can handle short
spikes of ±40 V.
NOTE: If the inputs are pulled up to +K, the
voltage range over which the digital inputs are
protected changes to +K – 36 V to +36 V.
Table 3. Counter/Timer Associations for BL4S100 Digital Input Pins
CAUTION: Do not allow the voltage on a digital input pin to exceed ±36 V to
avoid damaging the input.
