ZPP is a C++ wrapper for Zephyr so the OS API’s can be used more easily from C++.
It is not the intention of ZPP to implement a std:: library for Zephyr. ZPP tries to wrap the Zephyr C-API in C++20 without causing to much runtime and/or memory overhead.
ZPP tries to use RAII for things like locking and unlocking mutex’s comparable to the standard C++ library. Different from the standard C++ library ZPP does not use exceptions and it tries to not use dynamic memory allocation.

The MOS Technology 6581/8580 SID (Sound Interface Device) is the almost 40 year old sound chip that was used in the famous Commodore 64. It uses a 5bit address / 8bit data synchronous bus with a chip select, rw, and clock signal. Since the chip uses the 1MHz (well not exactly 1MHz as I’ll explain later) clock signal also to generate all the audio frequencies, so it is important that the clock signal is stable, even though the read/write access would work fine with a unstable clock as long as the signal setup times are correct.
