RS232-ADC16/24
Output frequency is calculated the following way :
f
output
= clock
SYS
/ 3 / 128 / 2
ADC cyles
.
2
Note : Output frequency is also limited by the selected baud rate. When using
49 MHz output frequency is set to 24.5 MHz.

For devices with at least firmware version 1.11 – default value for earlier
versions is 5.

Firmware versions below 1.11 use this formula :
f
output
= clock
ADC
/ 3 / 2
ADC cyles
, with clock
ADC
= 19200 Hz.

Baud rate select
Selects the baud rate used for serial transmission. The baud rate can be
choosen in five steps between 9600 and 115200 baud. Default baud rate is
115200. Any register setting above 4 will be interpreted as 4. After successful
command execution the boot message will be send using the new baud rate.
However the reply to the command is send with the old settings.
