4.16 CPPI DMA End of Interrupt Register (CPPIEOIR)

Note: This register was previously named TCPPIEOIR, and that name will continue to exist in the CSL for backward compatibility.

The CPPI DMA End of Interrupt Register (CPPIEOIR) is shown in Figure 31 and described in Table 32.

End of Interrupt Vector

 

 

This is an application specific register which is essentially a general purpose output from the LCSAR. One cycle after this register is written, the eoi_vector[7:0] value will appear on the eoi_vector output port from the LCSAR and the eoi_write output port will be asserted for 1 clock cycle. This register is used to convert level sensitive interrupts to pulsed, non-redundant interrupts. Software should write all zeros for the vector value.
