Delay after transfer scaler. The DT field selects the delay after transfer scaler. Use in master mode only. The delay
after transfer is the time between the negation of the PCS
x signal at the end of a frame and the assertion of PCS x
at the beginning of the next frame. The following table lists the scaler values.
The delay after transfer is a multiple of the system clock period. It is computed using the following equation:
Note: See Section 20.4.6.4, “Delay after Transfer (tDT) ,” for more details
