UART flow control reset
When the voltage of DS_input pin is maintained more than 10 seconds at 3.3V (high) during
system boot, UART flow control settings are reset to default values. The exact booting time
can be known by checking Ready Status of DS_ouput.
UART Flow control could be changed to no flow control after UART flow control settings are
reset. For more information, please refer to “IriShieldTM
-USB and IriShieldTM-UART SW
