(1) 100MHz GPMC_FCLK selected - CTRLMMR_GPMC_CLKSEL[0] CLK_SEL = 1 = MAIN_PLL2_HSDIV7_CLKOUT (100/60 MHz).
(2) Trace length from GPMC pins to device assumed to be less than 4" and length matched to within 200ps for 100MHz Synchronous Mode.
(3) In GPMC_WAIT[x], x is equal to 0 or 1.
(4) In div_by_1_mode, GPMC0_CLK refers to either GPMC0_CLKOUT or GPMC0_FCLK_MUX (free-running). Both signals are pin-muxed to the same pin.
GPMC_CONFIG1_i Register: GPMCFCLKDIVIDER = 0h:
– GPMC0_CLK frequency = GPMC_FCLK frequency
(5) In not_div_by_1_mode, GPMC_CLK only refers to GPMC0_CLKOUT. GPMC0_FCLK_MUX cannot be clock divided to match the GPMC0_CLKOUT frequency if GPMCFCLKDIVIDER > 0.
GPMC_CONFIG1_i Register: GPMCFCLKDIVIDER = 1h to 3h:
– GPMC_CLK frequency = GPMC_FCLK frequency / (2 to 4)
