Abstract
An electronic timekeeping circuit and a method for operating an electronic timekeeping circuit are described. In one embodiment, an electronic timekeeping circuit includes power supplies and timekeeping circuit components that are grouped into power supply domains. Power is supplied to each of the power supply domains by a corresponding one of the power supplies. Timekeeping registers are duplicated for each of the power supply domains. The timekeeping registers are synchronized between the power supply domains if one of the timekeeping registers is modified or if one of the power supplies is turned off and subsequently turned back on. Other embodiments are also described.
