In EDO mode
They are called tREA/tRHOH (NAND_RE_B access time/NAND_RE_B HIGH to output hold). The
typical value for them are 16 ns (max for tREA)/15 ns (min for tRHOH) at 50 MB/s EDO mode. In EDO
mode, GPMI will sample NAND_DATAxx at rising edge of delayed NAND_RE_B provided by an
internal DPLL. The delay value can be controlled by GPMI_CTRL1.RDN_DELAY (see the GPMI chapter
of the i.MX 6Dual/6Quad reference manual (IMX6DQRM)). The typical value of this control register is
0x8 at 50 MT/s EDO mode. However, if the board delay is large enough and cannot be ignored, the delay
value should be made larger to compensate the board delay.

NF16
NF17
The GPMI asynchronous mode output timing can be controlled by the module’s internal registers
HW_GPMI_TIMING0_ADDRESS_SETUP, HW_GPMI_TIMING0_DATA_SETUP, and HW_GPMI_TIMING0_DATA_HOLD.
This AC timing depends on these registers settings. In the table, AS/DS/DH represents each of these settings.
T = GPMI clock period -0.075ns (half of maximum p-p jitter).
NF12 is met automatically by the design.
Non-EDO mode.
EDO mode, GPMI clock  100 MHz
(AS=DS=DH=1, GPMI_CTL1 [RDN_DELAY] = 8, GPMI_CTL1 [HALF_PERIOD] = 0).
AS minimum value can be 0, while DS/DH minimum value is 1.
