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 0x8B45 AutoStore Disable
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 controlled or G controlled READ
operations must be performed:
Figure 4 - Current vs Cycle Time
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
If the AutoStore function is disabled or re-enabled,
a manual STORE operation (Hardware or Soft-
ware) needs to be issued to save the AutoStore
state through subsequent power down cycles. The
part comes from the factory with AutoStore
enabled.
