Embedded Component: NXPCMT
The carrier modulator transmitter (CMT) module provides a means to generate the protocol timing and carrier signals for a variety of encoding schemes. The CMT does not include dedicated hardware configurations for specific protocols but is intended to be sufficiently programmable in its function to handle the timing requirements of most protocols with minimal CPU intervention. The CMT consist of a carrier generator, modulator and transmitter which drives the infrared output pin. Modulation cycle consist of two parts: Mark and space.
