(10) First transfer only for CLK DIV 1 mode.

(11) Half cycle; for all data after initial transfer for CLK DIV 1 mode.

(12) Half cycle of GPMC_CLKOUT; for all data for modes other than CLK DIV 1 mode. GPMC_CLKOUT divide down from GPMC_FCLK.

(13) In GPMC_CSn[i], i is equal to 0, 1, 2 or 3. In GPMC_WAIT[j], j is equal to 0 or 1.

(14) P = GPMC_CLK period in ns

(15) Related to the GPMC_CLK output clock maximum and minimum frequencies programmable in the GPMC module by setting the

GPMC_CONFIG1_i configuration register bit field GPMCFCLKDIVIDER.

(16) 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 = 01 = PER1_PLL_CLKOUT / 3 = 300 / 3 = 100MHz

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)

For no extra_delay:

•

GPMC_CONFIG2_i Register: CSEXTRADELAY = 0h = CSn Timing control signal is not delayed

•

GPMC_CONFIG4_i Register: WEEXTRADELAY = 0h = nWE timing control signal is not delayed

•

GPMC_CONFIG4_i Register: OEEXTRADELAY = 0h = nOE timing control signal is not delayed

•

GPMC_CONFIG3_i Register: ADVEXTRADELAY = 0h = nADV timing control signal is not delayed

In GPMC_CSn[i], i is equal to 0, 1, 2 or 3.

In GPMC_WAIT[j], j is equal to 0 or 1.
