The ESAI provides a full-duplex serial port for serial communication with a variety of serial devices including one or more industry-standard codecs, other DSPs, microprocessors, and peripherals that implement the Motorola SPI serial protocol. The ESAI consists of independent transmitter and receiver sections, each with its own clock generator. It is a superset of the DSP56300 family ESSI peripheral and of the DSP56000 family SAI peripheral.
