20.6.3 Consecutive Data Writing to HIFRAM by External Device
Figure 20.5 shows the timing chart for consecutive data transfer from an external device to
HIFRAM. As shown in this timing chart, by setting the start address and the data to be written
first, consecutive data transfer can subsequently be performed.
