STK14EC8
Preliminary
The AutoStore can be re-enabled by initiating an
AutoStore Enable sequence. A sequence of READ
operations is performed in a manner similar to the
software RECALL initiation. To initiate the AutoStore
Enable sequence, the following sequence of E con-
trolled or G controlled READ operations must be
performed:
PREVENTING AUTOSTORE
The AutoStore function can be disabled by initiating
an AutoStore Disable sequence. A sequence of
READ operations is performed in a manner similar
to the software STORE initiation. To initiate the
AutoStore Disable sequence, the following
sequence of E controlled or G controlled READ
operations must be performed:
1 Read Address 0x4E38 Valid READ
2 Read Address 0xB1C7 Valid READ
3 Read Address 0x83E0 Valid READ
4 Read Address 0x7C1F Valid READ
5 Read Address 0x703F Valid READ
6 Read Address 0x4B46 AutoStore Enable
1 Read Address 0x4E38 Valid READ
2 Read Address 0xB1C7 Valid READ
3 Read Address 0x83E0 Valid READ
4 Read Address 0x7C1F Valid READ
5 Read Address 0x703F Valid READ
6 Read Address 0x8B45 AutoStore Disable
If the AutoStore function is disabled or re-enabled, a
manual STORE operation (Hardware or Software)
needs to be issued to save the AutoStore state
through subsequent power down cycles. The part
comes from the factory with AutoStore enabled, but
best design practice is to set the enable or disable
state during each power-up sequence and not
depend on this factory default condition. Simtek rec-
ommends users configure the part completely for
the specific application.
This is a product in development that has fixed tar-
get specifications that are subject to change pend-
ing characterization results.
