The M41T93 is a low-power serial SPI bus real-time clock (RTC) with a built-in 32.768 kHz oscillator (external crystal-controlled for the QFN16 package, and embedded crystal for the SOX18 package). Eight bytes of the register map are used for the clock/calendar function and are configured in binary coded decimal (BCD) format.

WitrynaOn microcontrollers with built-in SPI interfaces, an SPI control or configuration register will have bits that control the polarity and phase. Because the RTC supports either polarity, the polarity can be set as desired. The phase bit, however, must be set properly, or the RTC will not operate correctly. Figure 1 shows a typical single-byte ... Witryna6 sty 2024 · The RTC upon resetting Arduino or removing power to the RTC reverts to 1/1/2000. So when the DS3231 library code runs again, it indicates that the RTC had lost power and sets it to current date and time. This behaviour occours when there is a non-rechargeable 3v battery attached to the module.
