- 2.1 Communication Protocol
  
  This component is used to configure which communication protocol is being used for data transfer between the Bootloader and the Host application.
- 2.2 I/O Pins
  
  These components are used to enable the I/O operations the bootloader implements during execution.
- 2.3 Memory Verification Selector
  
  This component is used to set the verification method used for application verification.
- 2.4 Boot End Address
  
  This component is used to allow 8-bit PIC devices to configure where the bootloader section of Flash stops and the end application space begins.
- 2.5 Software Protection
  
  This component is used to activate a software method for write-protecting the bootloader section of Flash for 8-bit PIC devices.
- 2.6 Erase Type
  
  This component is used to configure the erase size for the bootloader’s erase action.
- 2.7 Optional Commands
  
  This section of the UI is used to initialize optional commands that the bootloader supports but does not require for basic operation.

Introduction

The MCC Melody Bootloader is a middleware library that is capable of configuring both 8-bit PIC® and AVR® bootloading solutions from a common UI. To properly configure bootloaders for any supported 8-bit device, the Bootloader Library needs to be able to handle different user input for each chip architecture. One of the most useful features of MCC Melody is the ability to query device information from within a module’s logic, something that MCC Classic was unable to achieve. The following sections detail the general design and usage of the 8-bit AVR and 8-bit PIC UI components given to the user by the bootloader module.

Note: Refer to the reference links shared in the Use Case Examples section or the Release Notes for information on the required dependencies and installation help.
