5.2.28 Processor Access Registers
The address space of the internal pico-processor (M3), used for DASL synchronization, can be accessed via
the Processor Address and Data Registers, along with the Processor Write and Processor Read commands
of the Command register.
To perform a write to a processor location:
1. Write the Processor Address register.
2. Write the Processor Data register.
3. Issue a Processor Write Command via the Command register.
To perform a read from a processor location:
1. Write to Processor Address register.
2. Issue a Processor Read Command via the Command register.
3. Read the Processor Data register.
The Processor Address auto-increments after every Processor Read or Write command, such that step (1)
only has to be performed once when consecutive locations are to be accessed.
