ARM9 microcontroller with CAN, LIN, and USB
A timing diagram for writing to external memory is shown In
Figure 6
. The relationship
between wait state settings is indicated with arrows.
WSTOEN = 3, WST1 = 6
Fig 5.
Reading from external memory
WSTWEN = 3, WST2 = 7
(1) BLS has the same timing as WE in configurations that use the byte lane enable signals to connect
to write enable (8 bit devices).
