Bus Controller (BC)
2 WE control/2 CAS control
DRAM that permits byte/word control can be supported by selecting either one of the following two methods:
• 2 WE control: The two pins WE1 and WE0 are used for byte/word control.
• 2 CAS control: The two pins DCAS1 and DCAS0 are used for byte/word control.
Fig. 8-14-3 illustrates an example of a write using 2 WE control, and Fig. 8-14-4 illustrates an example of a write
using 2 CAS control.
