Personality-module-micro-Code (PmmC)

One of the important features of the µ

DRIVE

module is the ability to upload its onboard

GOLDELOX processor with a micro-Code firmware which allows the module to take on a
new personality. This is referred to as Personality-module-micro-Code (PmmC). One of the
greatest benefits is that it allows the module to be easily upgraded by the user at any time
with PmmC files as further enhancements are made in the future. This allows the user to
benefit from those latest features.
