CONTROL (RTC) Register Bit-Field Summary
Field Name | Bits | Type | Reset Value | Description |
---|---|---|---|---|
Battery_Enable | 31 | woWrite-only | 0x0 | Enables the RTC. By writing a 0 to this bit, RTC will be powered off and the only module that potentially draws current from the battery will be BBRAM. The value read through this bit does not necessarily reflect whether RTC is enabled or not. It is expected that RTC is enabled every time it is being configured. If RTC is not used in the design, FSBL will disable it by writing a 0 to this bit. 0: RTC power off. 1: RTC power on. Read-only. |
