Abstract
Each of the identical register sets associated with each of the multiple channels of a peripheral device includes an initialization register. Setting the appropriate bit in the initialization register of any one of the channels allows the data processing system serviced by the peripheral device to perform a concurrent write operation to the same selected register in each channel enabled for a concurrent write. The concurrent write operation is based on a standard write instruction and a standard system address.
