Keyboard and Legacy GPIOs can only generate interrupts (no DMA requests). These
interrupts are cleared by writing inside the keyboard or legacy GPIOs registers. They are
masked in this block.
All other features managed by this block can generate interrupts. These interrupts are
cleared by a dummy byte access in the 0x5006xxxx area from the interrupt handler, and
masked by the mask register of this block.
I2S, TDM and end of line from camera interface can launch a DMA transfer. DMA transfer
are masked by the mask register of this block and cleared by the DMA controller (DMA_CLR
and DMA_TC signals).
