(1) The GNF12 parameter illustrates the amount of time required to internally sample input data. It is expressed in number of GPMC functional clock cycles. From start of the read cycle and after GNF12 functional clock cycles, input data is internally sampled by the active functional clock edge. The GNF12 value must be stored inside AccessTime register bit field.
(2) J = AccessTime × (TimeParaGranularity + 1) × GPMC_FCLK(3)
(3) GPMC_FCLK is general-purpose memory controller internal functional clock period in ns.
(4) For div_by_1_mode:
  • GPMC_CONFIG1_i Register: GPMCFCLKDIVIDER = 0h:
    • GPMC_CLK frequency = GPMC_FCLK frequency

For GPMC_FCLK_MUX:
  • CTRLMMR_GPMC_CLKSEL[1-0] CLK_SEL = 00 = CPSWHSDIV_CLKOUT3 = 2000/15 = 133.33MHz

For TIMEPARAGRANULARITY_X1:
  • GPMC_CONFIG1_i Register: TIMEPARAGRANULARITY = 0h = x1 latencies (affecting RD/WRCYCLETIME, RD/WRACCESSTIME, PAGEBURSTACCESSTIME, CSONTIME, CSRD/WROFFTIME, ADVONTIME, ADVRD/WROFFTIME, OEONTIME, OEOFFTIME, WEONTIME, WEOFFTIME, CYCLE2CYCLEDELAY, BUSTURNAROUND, TIMEOUTSTARTVALUE, WRDATAONADMUXBUS)
