    For WE rising edge (WE desactivated):

    - I = 0.5 × WEExtraDelay × GPMC_FCLK
    Case GpmcFCLKDivider = 1:
    - I = 0.5 × WEExtraDelay × GPMC_FCLK if (ClkActivationTime and WEOffTime are odd) or (ClkActivationTime and WEOffTime are even)
    - I = (1 + 0.5 × WEExtraDelay) × GPMC_FCLK otherwise

  11. J = GPMC_FCLK period, where GPMC_FCLK is the General Purpose Memory Controller internal functional clock
  12. For read:
    K = (ADVRdOffTime - ADVOnTime) × (TimeParaGranularity + 1) × GPMC_FCLK
    For write: K = (ADVWrOffTime - ADVOnTime) × (TimeParaGranularity + 1) × GPMC_FCLK
  13. The gpmc_clk output clock maximum and minimum frequency is programmable in the I/F module by setting the GPMC_CONFIG1_CSx configuration register bit fields GpmcFCLKDivider
  14. gpio6_16 programmed to MUXMODE=9 (clkout1), CM_CLKSEL_CLKOUTMUX1 programmed to 7 (CORE_DPLL_OUT_DCLK), CM_CLKSEL_CORE_DPLL_OUT_CLK_CLKOUTMUX programmed to 1.
  15. CSEXTRADELAY = 0, ADVEXTRADELAY = 0, WEEXTRADELAY = 0, OEEXTRADELAY = 0. Extra half-GPMC_FCLK cycle delay mode is not timed.
