NFC
The NAND flash controller (NFC) implements the interface to standard NAND flash memory devices. This section describes
the timing parameters of the NFC.
TH is the flash clock high time, TL is flash clock low time, where
TH = 5 × NFC_RATIO_H / 8 (ns)
Eqn. 6
TL = 5 × NFC_RATIO_L / 8 (ns)
Eqn. 7
Refer to the MPC5125 Reference Manual (MPC5125RM) for more information about NFC_RATIO_H and NFC_RATIO_L.
