| Size of the LSI measurement window (# of LSI periods) |
| |
| The measurement process involves waiting for a certain amount of LSI periods |
| to occur, in order to determine precisely the LSI period, and thus frequency. |
| |
| This property controls how much LSI periods are required for each measure. |
| Bigger window sizes increase accuracy of the measure, but increase the time |
| needed to complete it. Since fLSI >= 24kHz, increasing the measurement window |
| size makes each measure roughly 42µs slower in the worst case. |
| |
| Minimal value is a recommendation from RM0505 Rev.1 §25.8.2, and maximum |
| value is a hardware limitation. |

| int "LSI run-time measurement interval (ms)" |
| default 0 |
| help |
| Interval at which runtime measurements should be performed, in milliseconds |
| |
| Since the LSI RC frequency is affected by temperature, which is not stable |
| across time, it is recommended to perform measurements of the LSI frequency |
| at regular intervals to obtain better accuracy. |
| |
| This property enables runtime LSI measurement if present. In this case, |
| a background thread is created and performs LSI measurements, sleeping |
| the amount of time specified in this property between each measure. This |
| thread is also tasked with updating the control registers of peripherals |
| affected by slow clock drift such as RTC or IWDG, in collaboration with |
| the peripherals' drivers. Note that this increases the memory footprint |
| of the clock control driver, and may increase power consumption. |
| |
| Setting this option to the default value of "0" disables runtime frequency |
| measurements - the result of a single measure performed at boot will be |
| treated as LSI frequency for the lifetime of the application. |
