Monoshot Operation
The figure above illustrates the
operation of the monoshot when the
internal clock is set to divide by 2
mode, i.e., when A2=0, A1=0, and
A0=0. A rising edge on the internal
modulation state machine (IRTXD
OUTPUT), will cause the output on the

IRTXD to go up for 6 crystal clock
cycles. With a 3.6864 MHz clock, this
corresponds to a pulse of 1.63 s. The
duration of this pulse is independent
of the code A2, A1,A0 and is always 6
clock cycles of the crystal, corre-
sponding to the monoshot operation.
