Élan™SC310 Microcontroller Data Sheet 29
PRELIMINARY
All inputs that have VCC clamp = 5 V are 5-V safe inputs regardless of their VCCIO.
Notes:
1. These reset state entries identify the VCCIO levels that are present on the ÉlanSC310 microcontroller for the two bus mode
options. Note that the device is not limited to these VCC levels.
All inputs that have VCC clamp = 5 V are 5-V safe inputs regardless of their VCCIO.
