ADSP-BF531 / ADSP-BF532 / ADSP-BF533
The stopwatch function counts down from a programmed
value, with one second resolution. When the stopwatch is
enabled and the counter underflows, an interrupt is generated.
Like other peripherals, the RTC can wake up the processor from
sleep mode upon generation of any RTC wakeup event.
Additionally, an RTC wakeup event can wake up the processor
from deep sleep mode, and wake up the on-chip internal voltage
regulator from a powered-down state.
Connect RTC pins RTXI and RTXO with external components
TIMERS
There are four general-purpose programmable timer units in
the ADSP-BF531/ADSP-BF532/ADSP-BF533 processors. Three
timers have an external pin that can be configured either as a
pulse-width modulator (PWM) or timer output, as an input to
clock the timer, or as a mechanism for measuring pulse widths
and periods of external events. These timers can be synchro-
nized to an external clock input to the PF1 pin (TACLK), an
external clock input to the PPI_CLK pin (TMRCLK), or to the
internal SCLK.
The timer units can be used in conjunction with the UART to
RTXI

measure the width of the pulses in the data stream to provide an
autobaud detect function for a serial channel.
The timers can generate interrupts to the processor core provid-
ing periodic events for synchronization, either to the system
clock or to a count of external signals.
In addition to the three general-purpose programmable timers,
a fourth timer is also provided. This extra timer is clocked by the
internal processor clock and is typically used as a system tick
clock for generation of operating system periodic interrupts.
SUGGESTED COMPONENTS:
X1 = ECLIPTEK EC38J (THROUGH-HOLE PACKAGE) OR
EPSON MC405 12 pF LOAD (SURFACE-MOUNT PACKAGE)
C1 = 22 pF
C2 = 22 pF
R1 = 10 M
NOTE: C1 AND C2 ARE SPECIFIC TO CRYSTAL SPECIFIED FOR X1.
CONTACT CRYSTAL MANUFACTURER FOR DETAILS. C1 AND C2
SPECIFICATIONS ASSUME BOARD TRACE CAPACITANCE OF 3 pF.

WATCHDOG TIMER
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors
include a 32-bit timer that can be used to implement a software
watchdog function. A software watchdog can improve system
availability by forcing the processor to a known state through
generation of a hardware reset, nonmaskable interrupt (NMI),
or general-purpose interrupt, if the timer expires before being
reset by software. The programmer initializes the count value of
the timer, enables the appropriate interrupt, then enables the
timer. Thereafter, the software must reload the counter before it
counts to zero from the programmed value. This protects the
system from remaining in an unknown state where software,
which would normally reset the timer, has stopped running due
to an external noise condition or software error.
If configured to generate a hardware reset, the watchdog timer
resets both the core and the processor peripherals. After a reset,
software can determine if the watchdog was the source of the
hardware reset by interrogating a status bit in the watchdog
timer control register.
The timer is clocked by the system clock (SCLK), at a maximum
frequency of f SCLK .
SERIAL PORTS (SPORTs)
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors
incorporate two dual-channel synchronous serial ports
(SPORT0 and SPORT1) for serial and multiprocessor commu-
nications. The SPORTs support the following features:
? I 2 S capable operation.
? Bidirectional operation – Each SPORT has two sets of inde-
pendent transmit and receive pins, enabling eight channels
of I 2 S stereo audio.
? Buffered (8-deep) transmit and receive ports – Each port
has a data register for transferring data words to and from
other processor components and shift registers for shifting
data in and out of the data registers.
? Clocking – Each transmit and receive port can either use an
external serial clock or generate its own, in frequencies
ranging from (f SCLK /131,070) Hz to (f SCLK /2) Hz.
? Word length – Each SPORT supports serial data words
from 3 bits to 32 bits in length, transferred most-signifi-
cant-bit first or least-significant-bit first.
? Framing – Each transmit and receive port can run with or
without frame sync signals for each data word. Frame sync
signals can be generated internally or externally, active high
or low, and with either of two pulse widths and early or late
frame sync.
? Companding in hardware – Each SPORT can perform
A-law or μ-law companding according to ITU recommen-
dation G.711. Companding can be selected on the transmit
and/or receive channel of the SPORT without additional
latencies.
? DMA operations with single-cycle overhead – Each SPORT
can automatically receive and transmit multiple buffers of
memory data. The processor can link or chain sequences of
DMA transfers between a SPORT and memory.
