Data bus control
Figure 7-5 shows the ARM7TDMI data bus control timing. The timing parameters used
in Figure 7-5 are listed in Table 7-5.
The cycle shown in Figure 7-5 is a data write cycle because nENOUT was driven LOW
during phase one. Here, DBE has first been used to modify the behavior of the data bus,
and then nENIN.
