Signal

Description

AHB Bus

ARM920T processor AHB bus.

CSI_INT 

A CSI module interrupt signal is sent to the interrupt controller. CSI_INT is asserted 
when any CSI interrupt event is detected and is negated when the all interrupt 
sources are cleared or masked.

RxFIFO_DMAREQ

This DMA request signal is asserted when RxFIFO Full condition is true and is 
negated when RxFIFO Full condition becomes false.

STATFIFO_DMAREQ

This DMA request signal is asserted when STATFIFO Full condition is true and is 
negated when STATFIFO Full condition becomes false.
