must be written with A23 Low and the second two

with A23 High.

The first bus cycle sets up the Configure STS

command. A23 must be Low.

The second Bus Write cycle specifies one of the

four possible configurations, A23 must be Low,

(refer to Table 6, Configuration Codes):

– Ready/Busy mode

– Pulse on Erase complete mode

– Pulse on Program complete mode

– Pulse on Erase or Program complete mode

The third Bus Write cycle re-sets up the

Configure STS command. This time A23 must

be High.

The fourth re-specifies the configuration code

given in the second Bus Write cycle. A23 must

be High.

The device will not accept the Configure STS com-

mand while the Program/Erase controller is busy

or during Program/Erase Suspend. When STS pin

is pulsing it remains Low for a typical time of

250ns. Any invalid Configuration Code will set an

error in the Status Register.

The Configure STS command is not available with

the LFBGA88 package.
