Resetting the V
This procedure sets the V
level. For example, if the current V
V
TRIP
is reset, the new V
1.7V. This procedure must be used to set the voltage to
a lower value.

To reset the V
and 5.5V to the V
pin, and the SCK pin HIGH. RESET/RESET and SO
pins are left unconnected. Then apply the programming
voltage V

to the SI pin ONLY and pulse CS/WDI LOW
then HIGH. Remove V

and the sequence is complete.
