5. The PCB trace length of EMC_DQS[1:0] should be at least 2 inches (but not more
than 4 inches) longer than EMC_DQ[15:0] and EMC_DQM[1:0]. On a typical FR4
PCB this adds at least 334 ps to set-up time margin for DDR writes. For reads from
DDR the increased trace length of EMC_DQS[1:0] will be automatically compensated
for by the software initialization function find_ddr_dqsin_delay() which sets the optimal
value DDR_DQSIN_DELAY(SDRAMCLK_CTRL[6:2]). The function
find_ddr_dqsin_delay() can be found in the "DDR SDRAM setup code for the
LPC32x0 series" on the NXP web site.
