Detailed Description

struct timing_threshod - Timing threshold : The maximum number of data setup cycles that can be expressed in the hardware. : The time, in ns, that the NFC hardware requires for data read internal setup. In the Reference Manual, see the chapter "High-Speed NAND Timing" for more details. : The maximum sample delay factor that can be expressed in the hardware. : The maximum period of the GPMI clock that the sample delay DLL hardware can possibly work with (the DLL is unusable with longer periods). If the full-cycle period is greater than HALF this value, the DLL must be configured to use half-periods. : The maximum amount of delay, in ns, that the DLL can implement. : The clock frequency, in Hz, during the current I/O transaction. If no I/O transaction is in progress, this is the clock frequency during the most recent I/O transaction.
