9 GENERAL-PURPOSE PORTS

This chapter describes the general-purpose ports. Following an overview
and a list of key features is a block diagram of the interface and a descrip-
tion of operation. The chapter concludes with a programming model,
consolidated register definitions, and programming examples.

Overview

The ADSP-BF50x Blackfin processors feature a rich set of peripherals,
which, through a powerful pin multiplexing scheme, provides great flexi-
bility to the external application space.

Features

The peripheral pins are functionally organized into general-purpose ports
designated port F, port G, and port H.
Port F provides 16 pins:
• PPI data signals
• UART0 and UART1 signals
• SPORT0 signals
• SPI0 signals
• CNT0 (GP Counter 0) signals
