SOURCEREGISTER (SRC)
When the bit CM of command register is at one, this register contains the data to be written in the control
memory at the address indicated by the destination Register. It rappresents the address of the data
memory, or of one of the insertregister, correspondingto the input data to be switched to the output indi-
cated by the destinationregister.
Following you will find a detailed explanationcase by case of the meaningof all the bits of this register.
