The **Baudrate Prescaler** is used to determine the period of each time quantum by dividing the TWAI controller's source clock. On the {IDF_TARGET_NAME}, the ``brp`` can be **any even number from 2 to {IDF_TARGET_MAX_BRP}**. Alternatively, you can decide the resolution of each quantum, by setting :cpp:member:`twai_timing_config_t::quanta_resolution_hz` to a non-zero value. In this way, the driver can calculate the underlying ``brp`` value for you. It's useful when you set different clock sources but want the bitrate to keep the same.
