5.12 Register Version
Register Version is the number to identify if current version of software has any register changes relative
to previous versions: a register has been added or deleted, a register’s min/max limits have changed, a
register’s function has been changed, or a register’s default value has been changed. Generally it is the
programming parameters that are changed. Typically the Control Registers (AC TECH Register #1 through
#50) are quite stable.
