System Architecture

SPORT0 Interface

SPORT0 connects to the audio circuit, SPORT0 connector (P6), and expan- sion interface. The audio circuit uses the primary data transmit and receive pins to input and output data from the audio input and outputs.

SPORT1 and SPORT2 of the processor connect to the SPORT connectors (P3 and P4) and expansion interface.

The pinout of the SPORT interface and expansion interface connectors can be found in “ADSP-BF538FEZ-KIT Lite Schematic” on page B-1.

SPI Interface

The serial peripheral interface (SPI) of the processor connects to the SPI connectors (P1, P2, and P9) and expansion interface.

UART Interface

The UART interface of the processor connects to the UART connectors (P12, P14, and P15) and expansion interface.

Programmable Flags

The processor has 53 general-purpose input/output (GPIO) signals spread across four ports (PC, PD, PE, and PF). The pins are multi-functional and depend on the processor setup. Table 2-1shows how the programmable flag pins are used on the EZ-KIT Lite.
