339 / 1158 page  Section 6 Bus Controller (BSC) Rev.1.00 Jun. 07, 2006 Page 287 of 1102 REJ09B0294-0100 (3) When TRWL = 1 When the SDRAM interface is written to, one Trwl cycle is inserted after the Tc2 cycle. The DACK signal stays asserted until the end of the Trwl cycle. The hold time of data output from an external device can be extended by one cycle. Figure 6.86 shows an output timing example of the DACK signal when TRWL = 1 with DDS = 1 and DKC = 0.
