Description
The Tiva™ C Series TM4C123x family of ARM® Cortex™-M4 microcontrollers features highly programmable 5-V tolerant general-purpose input/outputs (GPIOs) with internal clamping and fail-safe electro static discharge (ESD) protection. The internal clamping and the fail-safe ESD protection require specific use conditions for external signal characteristics that must be followed at all times for proper
