0 = Changes to parameter settings (including P971)
are lost when power is removed.
1 = Changes to parameter settings are retained during periods
when power is removed.
IMPORTANT: When using the serial link to update the parameter set
held in EEPROM, care must be taken not to exceed the maximum number
of write cycles to this EEPROM - this is approximately 50,000 write
cycles. Exceeding this number of write cycles would result in corruption
of the stored data and subsequent data loss. The number of read cycles
are unlimited.
