Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Available DMA Channels Minus 1
This bit contains a value equal to the number of DMA channels the
controller is configured to use, minus one. That is, 32 DMA channels.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
