    The Board Support Packages (Microsoft) for our Trizeps-modules support different realtime-clocks; i.e.

    • PCF8563 same chip as EPSON RTC-8564 (recommended)

    • PCF8563

    • M41T81

    • DS1340

    • DS1629

    (see BSP for details of supported clocks) Of course support for other realtime-clocks can be added.

    Signals

    Most clocks use the I2C interface. Allthough the Trizeps already has pull-ups on these signals, designing additional pull-ups on the baseboard is recommended.
