... Mode Switching The TFDH6131 and TFDH6541 do not power on with a default mode, therefore the data transfer rate has to be set by a programming sequence using the Txd and SD/ Mode inputs as described below or selected by setting the Mode Pin. The Mode Pin can be used to statically set the mode (Mode Pin: LOW: SIR, HIGH ...
