Hello Radhika,

There are two main sources of Power on reset on TM4C

1. The VDD trip point which releases the device

2. The RST_N pin which when asserted low puts the device into Power On Reset

So when the VDD is ramping up, the device will be kept under reset till the threshold trip point is not reached. Once it crosses the trip points the device is accessible.

Amit
