I have also wondered if we should not replace SystemCoreClock with OS_CLOCK there too:

DAPLink/source/hic_hal/nxp/lpc4322/DAP_config.h

Line 55 in da0afc7

#define CPU_CLOCK SystemCoreClock ///< Specifies the CPU Clock in Hz

My guess is that when SystemCoreClock is used, its value is re-read it in case it was modified. (again, just a guess)

That's my guess too, but ideally we should be able to decide a frequency. The difference between a variable and a constant might be important in this case, because this is used by CMSIS-DAP for timing SWD/JTAG bit-banging.
