This page shows how the internal Real-time Clock (RTC) of the SAMA5D2 Series is enabled in the Linux® kernel and how to access the RTC in user space. First, a couple of concepts to explain before moving on: Wall clock: This is the Linux system clock. It was coded to run starting...
* the low-level rtc_read_alarm_internal() function. * * So, when the two timestamps disagree, we just loop and do * the process again to get a fully consistent set of values. * * This could all instead be done in the lower level driver, ...
• A pulse (≥ 30.5 μs) must be applied to the WAKEUP pin (active high). When the WAKEUP pin is asserted, the voltage on the DSP_LDOO pin will start ramping up and it is monitored by the internal POR. Until the voltage reaches to the threshold level, the internal POR will hold...
TN1396 Technical note RTC/API setup for wake-up in SPC58 family Introduction The aim of this document is to give recommendations for hardware designers using STMicroelectronics SPC58 lines devices for the correct usage of real-time clock / autonomous periodic interrupt (RTC/API) for wake-up ...
