ADSP-BF506F EZ-KIT Lite Evaluation System Manual

UART Setup Switch (SW1)

The UART setup switch (SW1) configures the UART0 signals between the

DCE connector (J1) and processor. Table 2-5 shows the switch settings.

Boot Mode Select Switch (SW2)

The boot mode select switch (SW2) determines the boot mode of the pro-

cessor. Table 2-5 shows the available boot mode settings. By default, the

ADSP-BF506F processor boots from SPI flash memory.
