(1) For single read: A = (CSRdOffTime - CSOnTime) * (TimeParaGranularity + 1) * GPMC_FCLK⁽¹⁴⁾

For single write: A = (CSWrOffTime - CSOnTime) * (TimeParaGranularity + 1) * GPMC_FCLK⁽¹⁴⁾

For burst read: A = (CSRdOffTime - CSOnTime + (n - 1) * PageBurstAccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK⁽¹⁴⁾

For burst write: A = (CSWrOffTime - CSOnTime + (n - 1) * PageBurstAccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK⁽¹⁴⁾

with n being the page burst access number

(2) For reading: B = ((ADVRdOffTime - CSOnTime) * (TimeParaGranularity + 1) + 0.5 * (ADVExtraDelay - CSExtraDelay)) *

GPMC_FCLK⁽¹⁴⁾

For writing: B = ((ADVWrOffTime - CSOnTime) * (TimeParaGranularity + 1) + 0.5 * (ADVExtraDelay - CSExtraDelay)) * GPMC_FCLK⁽¹⁴⁾

(3) C = ((OEOffTime - CSOnTime) * (TimeParaGranularity + 1) + 0.5 * (OEExtraDelay - CSExtraDelay)) * GPMC_FCLK⁽¹⁴⁾

(4) D = PageBurstAccessTime * (TimeParaGranularity + 1) * GPMC_FCLK⁽¹⁴⁾

(5) E = ((WEOnTime - CSOnTime) * (TimeParaGranularity + 1) + 0.5 * (WEExtraDelay - CSExtraDelay)) * GPMC_FCLK⁽¹⁴⁾

(6) F = ((WEOffTime - CSOnTime) * (TimeParaGranularity + 1) + 0.5 * (WEExtraDelay - CSExtraDelay)) * GPMC_FCLK⁽¹⁴⁾

(7) G = Cycle2CycleDelay * GPMC_FCLK⁽¹⁴⁾

(8) I = ((OEOffTime + (n - 1) * PageBurstAccessTime - CSOnTime) * (TimeParaGranularity + 1) + 0.5 * (OEExtraDelay - CSExtraDelay)) *

(9) J = (CSOnTime * (TimeParaGranularity + 1) + 0.5 * CSExtraDelay) * GPMC_FCLK⁽¹⁴⁾

(10) K = ((ADVOnTime - CSOnTime) * (TimeParaGranularity + 1) + 0.5 * (ADVExtraDelay - CSExtraDelay)) * GPMC_FCLK⁽¹⁴⁾

(11) L = ((OEOnTime - CSOnTime) * (TimeParaGranularity + 1) + 0.5 * (OEExtraDelay - CSExtraDelay)) * GPMC_FCLK⁽¹⁴⁾

(12) For single read: N = RdCycleTime * (TimeParaGranularity + 1) * GPMC_FCLK⁽¹⁴⁾

For single write: N = WrCycleTime * (TimeParaGranularity + 1) * GPMC_FCLK⁽¹⁴⁾

For burst read: N = (RdCycleTime + (n - 1) * PageBurstAccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK⁽¹⁴⁾

For burst write: N = (WrCycleTime + (n - 1) * PageBurstAccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK⁽¹⁴⁾

(13) In gpmc_csn[x], x is equal to 0, 1, 2, 3, 4 or 5.

(14) GPMC_FCLK is general-purpose memory controller internal functional clock period in ns.
