The HREFSEL bit in the GCR is used to set V
shown in the following table. The GCR contains trim bits that can be used to make
changes to the regulated voltage. The trim can be used to increase or decrease the
regulated voltage by 1.5% for each count. A total of ±12% of change can be done to the
regulated voltage.
