The ZLF645 MCU infrared timer features a 16-bit and an 8-bit counter/timer, each of
which can be used simultaneously for transmitting. Both timers can be used for demodu-
lating an input carrier wave and share a single input pin.

receiving and demodulating complex waveforms and pulses.
In addition to the 16-bit and 8-bit timers, the UART’s baud rate generator can be used as
an additional 8-bit timer when the UART receiver is not in use (for more details, see
