A third input can provide flexible zero marker support and can
alternatively be used to input the push-button signal of thumb
wheels. All three signals have a programmable debouncing
circuit.
An internal signal forwarded to the GP timer unit enables one
timer to measure the intervals between count events. Boundary
registers enable auto-zero operation or simple system warning
by interrupts when programmable count values are exceeded.
Serial Ports
The ADSP-BF51x processors incorporate two dual-channel syn-
chronous serial ports (SPORT0 and SPORT1) for serial and
multiprocessor communications. The SPORTs support the fol-
lowing features:
Serial port data can be automatically transferred to and from
on-chip memory/external memory via dedicated DMA chan-
nels. Each of the serial ports can work in conjunction with
another serial port to provide TDM support. In this configura-
tion, one SPORT provides two transmit signals while the other
SPORT provides the two receive signals. The frame sync and
clock are shared.
Serial ports operate in five modes:
• Standard DSP serial mode
• Multichannel (TDM) mode
•I2S mode
•Packed I2S mode
•Left-justified mode
Serial Peripheral Interface (SPI) Ports
The processors have two SPI-compatible ports (SPI0 and SPI1)
that enable the processor to communicate with multiple SPI-
compatible devices.
The SPI interface uses three signals for transferring data: two
data signals (master output-slave input–MOSI, and master
input-slave output–MISO) and a clock signal (serial
clock–SCK). An SPI chip select input signal (SPIxSS) lets other
SPI devices select the processor, and multiple SPI chip select
output signals let the processor select other SPI devices. The SPI
select signals are reconfigured general-purpose I/O signals.
Using these signals, the SPI port provides a full-duplex, syn-
chronous serial interface, which supports both master/slave
modes and multimaster environments.
The SPI port baud rate and clock phase/polarities are program-
mable, and it has an integrated DMA channel, configurable to
support transmit or receive data streams. The SPI’s DMA chan-
nel can only service unidirectional accesses at any given time.
UART Ports
The processors provide two full-duplex universal asynchronous
receiver/transmitter (UART) ports, which are fully compatible
with PC-standard UARTs. Each UART port provides a simpli-
fied UART interface to other peripherals or hosts, supporting
full-duplex, DMA-supported, asynchronous transfers of serial
data. A UART port includes support for five to eight data bits,
and none, even, or odd parity. Optionally, an additional address
bit can be transferred to interrupt only addressed nodes in
multi-drop bus (MDB) systems. A frame is terminates by one,
one and a half, two or two and a half stop bits.
The UART ports support automatic hardware flow control
through the Clear To Send (CTS) input and Request To Send
(RTS) output with programmable assertion FIFO levels.
To help support the Local Interconnect Network (LIN) proto-
cols, a special command causes the transmitter to queue a break
command of programmable bit length into the transmit buffer.
Similarly, the number of stop bits can be extended by a pro-
grammable inter-frame space.
The capabilities of the UARTs are further extended with sup-
port for the Infrared Data Association (IrDA®) serial infrared
physical layer link specification (SIR) protocol.
2-Wire Interface (TWI)
The processors include a TWI module for providing a simple
exchange method of control data between multiple devices. The
TWI is compatible with the widely used I2C
® bus standard. The
TWI module offers the capabilities of simultaneous master and
slave operation, support for both 7-bit addressing and multime-
dia data arbitration. The TWI interface utilizes two signals for
transferring clock (SCL) and data (SDA) and supports the pro-
tocol at speeds up to 400k bits/sec. The TWI interface signals
are compatible with 5 V logic levels.
Additionally, the processor’s TWI module is fully compatible
with serial camera control bus (SCCB) functionality for easier
control of various CMOS camera sensor devices.
Removable Storage Interface (RSI)
The RSI controller, available on the ADSP-BF514, ADSP-
BF516, ADSP-BF518, and ADSP-BF518F acts as the host inter-
face for multi-media cards (MMC), secure digital memory cards
(SD Card), secure digital input/output cards (SDIO), and CE-
ATA hard disk drives. The following list describes the main fea-
tures of the RSI controller.
• Support for a single MMC, SD memory, SDIO card or CE-
ATA hard disk drive
• Support for 1-bit and 4-bit SD modes
• Support for 1-bit, 4-bit and 8-bit MMC modes
• Support for 4-bit and 8-bit CE-ATA hard disk drives
• A ten-signal external interface with clock, command, and
up to eight data lines
• Card detection using one of the data signals
• Card interface clock generation from SCLK
• SDIO interrupt and read wait features
• CE-ATA command completion signal recognition and
disable
