Recently we migrated from HC12 (MC912DG128C) microcontroller to HCS12 (MC9S12XEG128CAL).

Checked the datasheet of MC9S12XEG128CAL controller and found that, this particular controller can also operate at 3.3V voltage level.

Currently we are using 5V power supply. Planned to migrate to 3.3V.

Please let me know whether this change will affect performance ?
