373 / 1504 page  Section 9 Bus Controller (BSC) Rev. 2.00 Sep. 24, 2008 Page 341 of 1468 REJ09B0412-0200 (3) When TRWL = 1 When the SDRAM interface is written to, one Trwl cycle is inserted after the Tc2 cycle. The DACK and EDACK signals stay 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 9.87 shows an output timing example of the DACK and EDACK signals when TRWL = 1 with DDS = 1, EDDS = 1, DKC = 0 and EDKC = 0.
