Figure 7.25 Basic Single Write Cycle Timing (Auto-Precharge) 7.5.6 Burst Write Mode Burst write mode can be selected by setting the BWE bit to 1 in BCR3. The basic timing charts for burst write access is shown in figure 7.26 (a) and (b). This example assumes a 32-bit bus width and a burst length of 4. In the burst write cycle, the WRITA command that performs auto- precharge is issued in Tc1 following the ACTV command Tr cycle. The first 4 bytes of write data are output simultaneously with the WRITA command in Tc1, and the remaining 12 bytes of data are output consecutively in Tc2, Tc3, and Tc4. In a write with auto-precharge, as with a single write, a Trw1 cycle that provides the waiting time until precharge is started is inserted after output of the write data, followed by a Tap cycle for the precharge wait in a write access. The Trw1 and |
