When the startup code initializes RTC_SLOW_CLK, it can perform
|
|
calibration by comparing the RTC_SLOW_CLK frequency with main XTAL
|
|
frequency. This option sets the number of RTC_SLOW_CLK cycles measured
|
|
by the calibration routine. Higher numbers increase calibration
|
|
precision, which may be important for applications which spend a lot of
|
|
time in deep sleep. Lower numbers reduce startup time.
|
|
|
|
When this option is set to 0, clock calibration will not be performed at
|
|
startup, and approximate clock frequencies will be assumed:
|
|
|
|
- 150000 Hz if internal RC oscillator is used as clock source. For this use value 1024.
|
|
- 32768 Hz if the 32k crystal oscillator is used. For this use value 3000 or more.
|
|
In case more value will help improve the definition of the launch of the crystal.
|
|
If the crystal could not start, it will be switched to internal RC.
