ADSP-BF531/ADSP-BF532/ADSP-BF533
During transfers, the SPI port simultaneously transmits and
receives by serially shifting data in and out on its two serial data
lines. The serial clock line synchronizes the shifting and sam-
pling of data on the two serial data lines.
UART PORT
The ADSP-BF531/2/3 processor provides a full-duplex Univer-
sal Asynchronous Receiver/Transmitter (UART) port, which is
fully compatible with PC-standard UARTs. The UART port
provides a simplified UART interface to other peripherals or
hosts, supporting full-duplex, DMA-supported, asynchronous
transfers of serial data. The UART port includes support for 5 to
8 data bits, 1 or 2 stop bits, and none, even, or odd parity. The
UART port supports two modes of operation:
PIO (Programmed I/O) – The processor sends or receives
data by writing or reading I/O-mapped UART registers.
The data is double-buffered on both transmit and receive.
DMA (Direct Memory Access) – The DMA controller
transfers both transmit and receive data. This reduces the
number and frequency of interrupts required to transfer
data to and from memory. The UART has two dedicated
DMA channels, one for transmit and one for receive. These
DMA channels have lower default priority than most DMA
channels because of their relatively low service rates.
The UART port's baud rate, serial data format, error code gen-
eration and status, and interrupts are programmable:
Supporting bit rates ranging from (f
SCLK
/ 1,048,576) to
(f
SCLK
/16) bits per second.
Supporting data formats from 7 to12 bits per frame.
Both transmit and receive operations can be configured to
generate maskable interrupts to the processor.
The UART port’s clock rate is calculated as:
Where the 16-bit UART_Divisor comes from the DLH register
(most significant 8 bits) and DLL register (least significant
8 bits).
In conjunction with the general-purpose timer functions, auto-
baud detection is supported.
The capabilities of the UART are further extended with support
for the Infrared Data Association (IrDA
) Serial Infrared Physi-
cal Layer Link Specification (SIR) protocol.
PROGRAMMABLE FLAGS (PFX)
The ADSP-BF531/2/3 processor has 16 bidirectional, general-
purpose Programmable Flag (PF15–0) pins. Each programma-
ble flag can be individually controlled by manipulation of the
flag control, status and interrupt registers:
Flag Direction Control Register – Specifies the direction of
each individual PFx pin as input or output.
Flag Control and Status Registers – The ADSP-BF531/2/3
processor employs a “write one to modify” mechanism that
allows any combination of individual flags to be modified
in a single instruction, without affecting the level of any
other flags. Four control registers are provided. One regis-
ter is written in order to set flag values, one register is
written in order to clear flag values, one register is written
in order to toggle flag values, and one register is written in
order to specify a flag value. Reading the flag status register
allows software to interrogate the sense of the flags.
Flag Interrupt Mask Registers – The two Flag Interrupt
Mask Registers allow each individual PFx pin to function as
an interrupt to the processor. Similar to the two Flag Con-
trol Registers that are used to set and clear individual flag
values, one Flag Interrupt Mask Register sets bits to enable
interrupt function, and the other Flag Interrupt Mask reg-
ister clears bits to disable interrupt function. PFx pins
defined as inputs can be configured to generate hardware
interrupts, while output PFx pins can be triggered by soft-
ware interrupts.
Flag Interrupt Sensitivity Registers – The two Flag Inter-
rupt Sensitivity Registers specify whether individual PFx
pins are level- or edge-sensitive and specify—if edge-sensi-
tive—whether just the rising edge or both the rising and
falling edges of the signal are significant. One register
selects the type of sensitivity, and one register selects which
edges are significant for edge-sensitivity.
PARALLEL PERIPHERAL INTERFACE
The processor provides a Parallel Peripheral Interface (PPI) that
can connect directly to parallel A/D and D/A converters, ITU-R
601/656 video encoders and decoders, and other general-pur-
pose peripherals. The PPI consists of a dedicated input clock
pin, up to 3 frame synchronization pins, and up to 16 data pins.
The input clock supports parallel data rates up to half the system
clock rate.
In ITU-R 656 modes, the PPI receives and parses a data stream
of 8-bit or 10-bit data elements. On-chip decode of embedded
preamble control and synchronization information is
supported.
Three distinct ITU-R 656 modes are supported:
Active Video Only - The PPI does not read in any data
between the End of Active Video (EAV) and Start of Active
Video (SAV) preamble symbols, or any data present during
