ADSP-2181
–4–
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-2181 is available in 128-lead TQFP and 128-lead
PQFP packages.

*These ADSP-2181 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-2181 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-
2181 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.
