Description
FLAG pins. Bidirectional input/output pins can be used as program conditions. Each pin
can be configured individually for input or for output. FLAG3–0 are inputs after power-up
and reset.
Interrupt Request. When asserted, the DSP generates an interrupt. Each of the IRQ3–0 pins
can be independently set for edge-triggered or level-sensitive operation. After reset, these
pins are disabled unless the IRQ3–0 strap option and interrupt vectors are initialized for
booting.
Timer 0 expires. This output pulses whenever timer 0 expires. At reset, this is a strap pin.

Link Ports 3–0 Data 3–0 Transmit LVDS N
Link Ports 3–0 Transmit Clock LVDS P
Link Ports 3–0 Transmit Clock LVDS N
Link Ports 3–0 Receive Acknowledge. Using this signal, the receiver indicates to the
transmitter that it may continue the transmission.
Link Ports 3–0 Block Completion. When the transmission is executed using DMA, this
signal indicates to the receiver that the transmitted block is completed. The pull-up
resistor is present on L0BCMPO only. At reset, the L1BCMPO, L2BCMPO, and L3BCMPO
pins are strap pins. For more information, see
