whether the data is set up for a block write. Undesirable results
may be observed if the device’s V
during this process.
In the event that the module experiences a fault and power is
lost, the user can extract the last SNAPSHOT parameters stored
during the fault by writing a 1 to SNAPSHOT_CONTROL (transfers
data from Flash memory to RAM) and then issuing a SNAPSHOT
command (reads data from RAM via SMBus).

Non-Volatile Memory and Device Security
Features
The ZL9101M has internal non-volatile memory where user
configurations are stored. Integrated security measures ensure
that the user can only restore the module to a level that has been
made available to them.
During the initialization process, the ZL9101M checks for stored
values contained in its internal non-volatile memory. The
ZL9101M offers two internal memory storage units that are
accessible by the user as follows:
Please refer to Application Note
specific security measures via the I
1. Default Store: The ZL9101M has a default configuration that
2. User Store: The user can modify certain power supply settings

be restored to its default settings by issuing a
RESTORE_DEFAULT_ALL command over the SMBus.
as described in this data sheet. The user would use the User
