Abstract:	ATLAS Electronics Notes University of Michigan Physics Randall Laboratory TO: ATLAS Muon Front-end Electronics Group FROM: J. Chapman RE: How to use new synchronize watches function of AMT-1 MiniDaq CC: All CSM-0 Users Purpose of the added code The AMT-1 has been observed to powerup in two different states that result in digitizations that are 12.5ns different. However, for the ASD-lite boards, it was necessary to add a JTAG instruction (5) that resets the AMT-1 using the JTAG clock which is derived from the external 40Mhz clock and thus in a fixed phase relative to it. The reset_clock function works by construction of a linked list of JTAG strings that are few to the JTAG loop using ...
