Getting Started with ADSP-BF548 EZ-KIT Lite 3-3
Using ADSP-BF548 EZ-KIT Lite Peripherals
and other peripherals. The interface is configurable and sup-
ports data widths up to 24 bits. The ADSP-BF548 processor
can support up to three EPPI interfaces.
• Industry-standard ATA/ATAPI-6 interface. An
ATA/ATAPI-6 interface is for control of a CD, DVD, hard
disk drive, or any other ATAPI-compatible device.
3. Specialized interfaces
• Host DMA port. A host DMA port allows an external pro-
cessor to control DMA transfers to and from an
ADSP-BF548 system.
• Secure digital (SD) I/O controller
• Controller Area Network (CAN) controllers. The CAN
controllers implement the CAN 2.0B (active) protocol. The
processor supports up to two CAN controllers.
4. Miscellaneous interfaces
• A 32-bit up/down counter interface for standard manual
rotary switches and mechanical drives
• A keypad interface supporting a matrix of up to 8 x 8 keys
• General-purpose I/O (GPIO) pins. Individual pins from
any unused processor peripheral can be used as input or out-
put data signals. The pins can be configured as edge- or
level-sensitive and used in a polled- or interrupt-driven
manner. The GPIO pins also are called the programmable
flags (PFs).
