Figure 12-44. MCU Connected to Asynchronous Memory
shows a timing diagram of a read operation to a 16-bit asynchronous memory using three
wait states.
Figure 12-45. Read Operation to Asynchronous Memory, Three Initial Wait States
Flash memories typically use one WE signal as shown.

Memory
Note:
On a 32-bit bus, RAM memories use all four WE/BE[0:3]. On a 16-bit bus, one
RAM memory uses WE/BE[0:1] and the other uses WE/BE[2:3].
