The IR Detection Circuit
It only takes one IR detector to capture messages from the IR remote (see Figure 1-6).
Measuring Start and Data Pulses
The
complementary command called
Pin
determine whether the pulse is a high pulse (1) or a low pulse (0).

√
PULSOUT
is, of course, used to select the I/O pin for measuring the pulse.
