ADSP-2185M
–5–
external buses with bus request/grant signals (
BR, BGH, and BG).
One execution mode (Go Mode) allows the ADSP-2185M to
continue running from on-chip memory. Normal execution
mode requires the processor to halt while buses are granted.
The ADSP-2185M can respond to eleven interrupts. There can
be up to six external interrupts (one edge-sensitive, two level-
sensitive, and three configurable) and seven internal interrupts
generated by the timer, the serial ports (SPORTs), the Byte DMA
port, and the power-down circuitry. There is also a master
RESET signal. The two serial ports provide a complete synchro-
nous serial interface with optional companding in hardware and
a wide variety of framed or frameless data transmit and receive
modes of operation.
Each port can generate an internal programmable serial clock or
accept an external serial clock.
The ADSP-2185M provides up to 13 general-purpose flag pins.
The data input and output pins on SPORT1 can be alternatively
configured as an input flag and an output flag. In addition, eight
flags are programmable as inputs or outputs, and three flags are
always outputs.
A programmable interval timer generates periodic interrupts.
A 16-bit count register (TCOUNT) decrements every n pro-
cessor cycle, where n is a scaling value stored in an 8-bit register
(TSCALE). When the value of the count register reaches zero,
an interrupt is generated and the count register is reloaded from
a 16-bit period register (TPERIOD).
Serial Ports
The ADSP-2185M incorporates two complete synchronous
serial ports (SPORT0 and SPORT1) for serial communications
and multiprocessor communication.
Here is a brief list of the capabilities of the ADSP-2185M
SPORTs. For additional information on Serial Ports, refer to
the ADSP-2100 Family User’s Manual.
SPORTs are bidirectional and have a separate, double-
buffered transmit and receive section.
SPORTs can use an external serial clock or generate their
own serial clock internally.
SPORTs have independent framing for the receive and trans-
mit sections. Sections run in a frameless mode or with frame
synchronization signals internally or externally generated.
Frame sync signals are active high or inverted, with either of
two pulsewidths and timings.
SPORTs support serial data word lengths from 3 to 16 bits
and provide optional A-law and
-law companding according
to CCITT recommendation G.711.
SPORT receive and transmit sections can generate unique
interrupts on completing a data word transfer.
SPORTs can receive and transmit an entire circular buffer of
data with only one overhead cycle per data word. An interrupt
is generated after a data buffer transfer.
SPORT0 has a multichannel interface to selectively receive
and transmit a 24 or 32 word, time- division multiplexed,
serial bitstream.
SPORT1 can be configured to have two external interrupts
(
IRQ0 and IRQ1) and the FI and FO signals. The internally
generated serial clock may still be used in this configuration.
PIN DESCRIPTIONS
The ADSP-2185M is available in a 100-lead LQFP package
and a 144-Ball Mini-BGA package. In order to maintain maxi-
mum functionality and reduce package size and pin count, some
serial port, programmable flag, interrupt and external bus pins
have dual, multiplexed functionality. The external bus pins are
configured during
RESET only, while serial port pins are soft-
ware configurable during program execution. Flag and interrupt
functionality is retained concurrently on multiplexed pins. In
cases where pin functionality is reconfigurable, the default state is
shown in plain text; alternate functionality is shown in italics.
