# Register descriptions
#
# All description must be put in the regs-namespace. Each register concist
# of a name, description and an optional list of fields.
# The fields are quadruple of the format {name pos bits description}
#
# Registers and fields can be added, removed or changed up to initialization
# level 8. After level 8 TCL variables are created and the regs variable
# should be considered to a constant.

5. User defined commands
User defined commands can be implemented as Tcl procedures, and then loaded into all shells. See the docu-
mentation of the proc command [http://www.tcl.tk/man/tcl8.6/TclCmd/proc.htm] on the Tcl website for more in-
formation.
