A.4.1. Reset

Reset precedes the boot stages and is an important part of device initialization. There are two different reset types: cold reset and warm reset.

The boot process begins when the CPU in the MPU exits from the reset state. When the CPU exits from reset, it starts executing code at the reset exception address where the boot ROM code is located.

With warm reset, some software registers are preserved and the boot process may skip some steps depending on software settings. In addition, on a warm reset, the preloader has the ability to be executed from on-chip RAM.
