Additional Information
Command Controls
and Signals
The following common control signals operate on all modules
within the crate, without requiring address by a command.
Initialize
Inhibit
The initialize signal (Z) has absolute priority over all other sig
nals or controls. It sets all units to a basic state by resetting all
registers, and by resetting all LAM signals and disabling them
where possible.
The presence of this signal (I) can be used by a module to in
hibit any activity (for example, data-taking).
Clear
The common clear signal (C) resets all registers and bistables
connected to it.
