 * ESP32-H21 cache profile counter units.
 *
 * Single cache level shared by instructions and data (the flash cache),
 * with two request buses: bus0 carries instruction fetches, bus1 carries
 * data accesses (same bus arrangement as the ESP32-C5). The cache is
 * read-only (no PSRAM, no write-back — see SOC_CACHE_WRITEBACK_SUPPORTED),
 * so no write-back counters are exposed.
