    /* PAGEs 1 and onwards are for overlay purposes for memory optimization.
       Some examples:
       1. Overlay one-time only text with uninitialized data.
       2. Overlay L1PSRAM data path processing fast code and use copy tables
          to page in (before entering data path) and out of L1PSRAM (when entering
          sleep/low power).
