High Priority Access (HPA) is a 12-month maintenance service providing unlimited PRO optimizations for all MPLAB® XC compiler versions, priority technical support for compiler-related queries, and free shipping of development tools that you order on Microchip’s Purchasing and Client Services e-commerce website. After HPA is purchased, it must be applied to a compiler and downloaded for it to start. The 12-month HPA will start on the date it is applied to the compiler or the date a current HPA expires, whichever is later.
Upon the expiration of your current HPA subscription:
All MPLAB XC Compilers come with one full year of HPA, and no further purchases or activations are necessary. For information on purchasing and activating your MPLAB XC HPA renewal, please download or review the MPLAB XC HPA Renewal Instructions, found in the documentation tab of the MPLAB XC Compilers page.
