— Enhanced Serial Audio Interface I (ESAI_1): up to 4 receivers and up to 6 transmitters, master
— Serial Host Interface (SHI): SPI and I
— Triple Timer module (TEC).
— 11 dedicated GPIO pins
— Digital Audio Transmitter (DAX): 1 serial transmitter capable of supporting the SPDIF,
— Pins of unused peripherals (except SHI) may be programmed as GPIO lines
The DSP56300 core is composed of the Data ALU, Address Generation Unit, Program Controller,
DMA Controller, Memory Module Interface, Peripheral Module Interface and the On-Chip
Emulator (OnCE). The DSP56300 core is described in the document <st-blue>DSP56300 24-Bit
