Host transport selection
DFBM-CS320
The firmware configures itself when it boots by reading the values on a set of PIO pins.

(*1) If a UART-based host transport is selected and the firmware does not know its clock
frequency (because PSKEY_ANA_FREQ contains no value), then the firmware attempts to lock
on to the available system clock signal. Use of this mechanism implies booting the firmware
twice, as described in [AUTOBAUD]. PSKEY_ANA_FREQ has no default value.
(*2) If a UART-based host transport is selected and the baud rate defined in
PSKEY_UART_BAUDRATE is zero (the default value), then the baud rate adaptation process
is invoked, as described in [AUTOBAUD].
If the PS Key contains a non-zero baud rate then the UART is configured with this value. If
the system clock adaptation mechanism is used, it may result in the processor running slower
than normal, so the consequent (measured) baud rate will also be affected.
