ADSP-2183
–4–
REV. C
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 Flag In and Flag Out signals. The
internally generated serial clock may still be used in this
configuration.
Pin Descriptions
The ADSP-2183 is available in a 128-lead LQFP package, and
Mini-BGA.

*These ADSP-2183 pins must be connected only to the EZ-ICE connector in
the target system. These pins have no function except during emulation, and
do not require pull-up or pull-down resistors.
Interrupts
The interrupt controller allows the processor to respond to the
eleven possible interrupts and reset with minimum overhead.
The ADSP-2183 provides four dedicated external interrupt
input pins,
IRQ2, IRQL0, IRQL1 and IRQE. In addition,
SPORT1 may be reconfigured for
IRQ0, IRQ1, FLAG_IN and
FLAG_OUT, for a total of six external interrupts. The ADSP-
2183 also supports internal interrupts from the timer, the byte
DMA port, the two serial ports, software and the power-down
control circuit. The interrupt levels are internally prioritized and
individually maskable (except power-down and reset). The
IRQ2, IRQ0 and IRQ1 input pins can be programmed to be
either level- or edge-sensitive.
IRQL0 and IRQL1 are level-
sensitive and
IRQE is edge sensitive. The priorities and vector
addresses of all interrupts are shown in Table I.
