High Priority Access 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.
Your existing compiler license will revert to the free optimizations after your current HPA expires. If you let your HPA lapse, there are no extra fees. You can pick up HPA to renew your PRO optimizations and other HPA benefits at any time.
All newly purchased MPLAB XC Compilers come with one full year of HPA and no further purchases or activations are necessary. However, HPA must be purchased to continue using the PRO mode optimizations of the compiler.
For information on purchasing and activating your MPLAB XC HPA renewal refer to the MPLAB XC HPA Renewal Instructions.
