help
To reduce the startup time of an external RTC crystal,
we bootstrap it with a 32kHz square wave for a fixed number of cycles.
Setting 0 will disable bootstrapping (if disabled, the crystal may take
longer to start up or fail to oscillate under some conditions).
If this value is too high, a faulty crystal may initially start and then fail.
If this value is too low, an otherwise good crystal may not start.
To accurately determine if the crystal has started,
set a larger "Number of cycles for RTC_SLOW_CLK calibration" (about 3000).
