9.6.1 AES_DMAIM Register (Offset = 0x20) [reset = 0x0]
AES DMA Interrupt Mask (AES_DMAIM)
The AES DMA Interrupt Mask (AES_DMAIM) register controls interrupt behavior and is used to program which interrupts are suppressed.
AES_DMAIM is shown in Figure 9-27 and described in Table 9-23.

DOUT |
R/W |
0x0 |
Data Out DMA Done Interrupt Mask.
If this bit is unmasked, an interrupt is generated when the µDMA writes the last word of the process result.
0x0 = The DOUT interrupt is suppressed and not sent to the interrupt controller.
0x1 = The DOUT interrupt is sent to the interrupt controller.
|
2 |
DIN |
R/W |
0x0 |
Data In DMA Done Interrupt Mask.
If this bit is unmasked, an interrupt is generated when the µDMA writes the last word of input data to the internal FIFO of the engine.
0x0 = The DIN interrupt is suppressed and not sent to the interrupt controller.
0x1 = The DIN interrupt is sent to the interrupt controller.
|
1 |
COUT |
R/W |
0x0 |
Context Out DMA Done Interrupt Mask.
If this bit is unmasked, an interrupt is generated when the µDMA completes the output context read from the internal register.
0x0 = The COUT interrupt is suppressed and not sent to the interrupt controller.
0x1 = The COUT interrupt is sent to the interrupt controller.
|
0 |
CIN |
R/W |
0x0 |
Context In DMA Done Interrupt Mask.
If this bit is unmasked, an interrupt is generated when the µDMA completes a context write to the internal register.
0x0 = The CIN interrupt is suppressed and not sent to the interrupt controller.
0x1 = The CIN interrupt is sent to the interrupt controller.
