Register maps

In this section the control and status register definitions of each gateware design in the dogma system are listed:

DOGMA_HUB1_DCM

The Dogma Controller Module is the central controller of the Dogma daq system. It distributes the 100MHz Dogma system clock and the trigger signals to all connected dogs (can also be subsequent hubs for higher fanout) and collects daq control signals (raw triggers from front-ends, trigger flow control). It also hosts the central trigger system (trigger priorisation, dead-time).
