The multichannel audio serial port (McASP) primer

This training series focuses on hardware design for the McASP.

This training series focuses on hardware design for multichannel audio serial port (McASP). Before an engineer gets around to writing software for McASP, it has to be wired up properly. That is the focus of this McASP primer.

All examples provided in this training assume that McASP is connecting to audio devices using the I2S (Inter-IC Sound) protocol. This is somewhat arbitrary, as the physical hookup of McASP to an audio device using multi-slot time division-multiplexed (TDM) or using I2S is the same.

This training is intended to cover McASP at a high level, across all of our devices, rather than McASP on a specific device. The technical reference manual (TRM) for your device is the best place to go for architectural and chip-level implementation details.
