336 / 1504 page ![]() Section 9 Bus Controller (BSC) Rev. 2.00 Sep. 24, 2008 Page 304 of 1468 REJ09B0412-0200 (1) When DDS = 1 or EDDS = 1 A fast-page access is performed regardless of the bus master, only according to the address. The DACK and EDACK signals are asserted at the start of the Tc1 cycle. Figure 9.58 shows the output timing example of the DACK and EDACK signals when DDS = 1 or EDDS = 1.
