Status indication detection device and method

The state indication detecting device (SIDM) comprises an input memory layer (INS) and supplementary storage layer (ISS) and an memory layer (OSS). State indicator (IN_STATUS) to an input memory layer (INS) input register (INM), and shifting to the complementary storage layer and rechargeable battery is at the output memory layer (ISS and OSS). The input and supplementary storage layer of the second reference (CLK-A) and a first clock domain (A), the output memory layer and second clock domain (B) with different second reference (CLK-B) and. According to the invention, and possibly and generating a signal LOCK () is arranged supplementary storage layer (ISS) is register (INT), a signal LOCK () of the current state indicator (supplementary a storage layer (ISS), and preventing the new state indication from the input memory layer (INS) transmits. Layer which the signal LOCK () duration at least one second reference clock cycle, therefore read pulse (STROBE) is put in which a signal duration (LOCKL). The invention claims an, comprising a first and second reference (CLK-A and CLK-B) and different phase and/or the frequency relations, capable of avoid output register (0RM) is metastable, and transmits the two any state indicator of hardware device (HW) is.
