In Host Mode the appropriate bits are set in the command mode
Hardware Mode
Clock Edge:
In Hardware Mode, connect this pin "Low" to select falling edge of TxClk to
sample input data and also select RxPOS/RxNEG data will be changed on
the falling edge of RxClk. Connect this pin "High" to select rising edge of
TxClk to sample input data and also selects RxPOS/RxNEG data to be
updated on the rising edge of RxClk.
