A Multichannel Audio Serial Port (McASP) is a communication peripheral in digital signal processor (DSP) and microcontroller unit (MCU) components from Texas Instruments. An McASP functions as a general-purpose audio serial port optimized for the needs of multichannel audio applications. Depending on the implementation, an McASP may be useful for time-division multiplexed (TDM) streaming, inter-integrated circuit sound (I2S) protocol, and intercomponent digital audio interface transmission (DIT). However, some implementations are limited to I2S. An McASP consists of transmit and receive sections that may operate synchronized, or completely independently with separate master clocks, bit clocks, and frame syncs, and using different transmit modes with different bit-stream formats. An McASP module also includes up to 16 serializers that can be individually enabled to either transmit or receive. In addition, all of the McASP pins can be configured as general-purpose input/output (GPIO) pins.
