INTRODUCTION TO BOOT ROM
Boot ROM stands for Boot Read-Only Memory. It is
a type of read-only program that stores in the
ROM as firmware or software that runs when you
turn on your computer. The firmware is also
known as BIOS (Basic Input/output System) or
UEFI (Unified Extensible Firmware Interface),
depending on the type of your computer.

ARCHITECTURE OF BOOT ROM

• The architecture of Boot ROM, or Boot Read-Only
  Memory, is a fundamental component in the
  startup process of microcontrollers or
  microprocessors.
• Initialization
• Read-Only Memory Space
• Specialized Functions
• Boot Mode Activation
• External Communication
• Application Software Reception
• NVM Memory Interaction
• Permanent Code
• Device Customization

TYPES OF BOOT ROM
There are two types of boot ROM used in Embedded
Systems. Mask boot ROM Cannot be changed
afterward. Boot EEPROM Can contain a UEFI
implementation.

HOW DOES BOOT ROM WORK IN A MICROCONTROLLER?
Boot ROM serves as a compact yet pivotal program
meticulously crafted by the chip
manufacturer. Designed with a singular purpose,
it remains steadfast in the boot mode, ready to
engage when an external computer system connects
through the serial (UART) port.
