To reduce the startup time of an external RTC crystal,

we bootstrap it with a 32kHz square wave for a fixed number of cycles.

The app's maximum baud rate depends on the UART clock source. If Power Management is disabled,

|
|
the UART clock source is the APB clock and all baud rates in the available range will be sufficiently

accurate. If Power Management is enabled, REF_TICK clock source is used so the baud rate is divided
|
|

from 1MHz. Baud rates above 1Mbps are not possible and values between 500Kbps and 1Mbps may not be
