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 (IR_TXD output), will cause the
output on the IR_TXD to go up for 6 crystal clock cycles.
With a 3.6864 MHz clock, this corresponds to a pulse of
1.63 µs. The duration of this pulse is independent of the
code A2, A1, A0 and is always 6 clock cycles of the crystal,
corresponding to the monoshot operation.
