Keep the following guidelines in mind when selecting special uses for the digital input pins.
• Interrupts, event counters, and input capture are available on any digital input pin.
• Each Quadrature Decoder channel requires at least two digital input pins associated
Sample programs in the
use digital inputs for interrupts, pulse capture, and quadrature decoders.
3.2.1.1 Interrupt, Counter, and Event Capture Setup
External interrupts on the BL4S100 digital input pins are configured using the

The counter readings can be obtained via the
BL4S100 User’s Manual
An input channel may be set up to count
events, with the count incrementing or
decrementing, using the rising edge, fall-
ing edge, or either edge as triggers to start/
end the count. This feature is configured
using the

ticular clock cycle is noted at the start of the
event and at the end of the event so that the
time between them can be determined. This
can be set up on one or two input channels.
The event counter can be reset with the

counter/timer block are needed if you need indexing. Quadrature Decoder channels are
