25.3.2 SHA_DMARIS Register (Offset = 0x14) [reset = 0x0]
SHA DMA Raw Interrupt Status (SHA_DMARIS)
The SHA DMA Raw Interrupt Status (SHA_DMA_RIS) register contains the raw interrupt status. If any of these bits read 1, the processor is interrupted if the corresponding masked interrupt status bit is set to 1.
SHA_DMARIS is shown in Figure 25-15 and described in Table 25-28.
