NV Writes Deferred
A high number of writes has been detected to non-volatile
memory. To prevent premature failure of the memory, the
write operations have been deferred. The data will be saved
on a 6 hour cycle. This condition usually exists because a
program has been written that writes to function block
parameters not normally expected to be written to on a cyclic
basis. Any such automated write sequence should be modified
to write the parameter(s) only when needed. It is
recommended that you limit the number of periodic writes to all
static or non-volatile parameters such as HI_HI_LIM,
LOW_CUT, SP, TRACK_IN_D, OUT, IO_OPTS, BIAS,
STATUS_OPTS, SP_HI_LIM, and so on.

Lost Deferred NV Data
Device has been power_cycled while non_volatile writes were
being deferred to prevent premature memory failure. This has
resulted in the loss of static/non-volatile data before it could be
saved in non-volatile memory.
1. Check the device configuration for changes in the block
parameter values.
2. Reset the device to clear the error.
3. See the help for NV writes Deferred for details of preventing
problem again.
