9 Enhanced Serial Audio Interface 1 (ESAI_1)
9.1 Introduction
The Enhanced Serial Audio Interface I (ESAI_1) is the second ESAI peripheral in the DSP56366. It is
functionally identical to the ESAI peripheral described in Section 8, "Enhanced Serial AUDIO Interface
(ESAI)" except for minor differences described in this section. Refer to the ESAI section for functional
information about the ESAI_1, in addition to using the information in this section.
The ESAI_1 block diagram is shown in Figure 9-1. The ESAI_1 shares 4 pins with the ESAI. The ESAI_1
does not have the two high frequency clock pins but otherwise it is identical to the ESAI.
