◆ CONFIG_ZTIMER_PERIPH_TIMER_FORCE_CONVERSION

#define CONFIG_ZTIMER_PERIPH_TIMER_FORCE_CONVERSION   1

Force frequency conversion to be used.

Otherwise ztimer would assume that it can run the 1 MHz clock from the timer configured at 1 MHz without conversion. But the actual frequency the timer will run at will be detected at runtime and, due to inaccuracy of the internal oscillator, will indeed require frequency conversion.
