Programmable Registers
Address:
Re-
22.8.10 Persistent State Register 3 (HW_RTC_PERSISTENT3)
The 32-bit persistent registers are used to retain certain control states during chip-wide
power-down states.
HW_RTC_PERSISTENT3: 0x090
HW_RTC_PERSISTENT3_SET: 0x094
HW_RTC_PERSISTENT3_CLR: 0x098
HW_RTC_PERSISTENT3_TOG: 0x09C
The register initalizes to a known reset pattern. The copy controller overwrites this digital
reset value very soon after power on but not in zero time.
