4.9.1 GPMI Asynchronous mode AC timing (ONFI 1.0 compatible)
Asynchronous mode AC timings are provided as multiplications of the clock cycle and fixed delay. The
Maximum I/O speed of GPMI in Asynchronous mode is about 50 MB/s. Figure 9 through Figure 12 depict
the relative timing between GPMI signals at the module level for different operations under Asynchronous
mode. Table 45 describes the timing parameters (NF1–NF17) that are shown in the figures.
