Functional Overview

For t

• when using memory devices that are not wait-enabled, you must program t

be the number of clock cycles required before the first data is written, following

the assertion of cs_n

• when using memory devices that are wait-enabled, you must program t

to be

the number of clock cycles required before wait is active and stable, following the

assertion of cs_n. That is:

t_WC = 3

Note

If a memory device is configured so that there are two or less clock cycles

between the assertion of wait and data being required then you must program t

as if the memory device is not wait-enabled.
