Initial State
reset to a known state. This is referred to as the Initial state. All
the bit field locations that have intact fuses are set to logic 0.
While in the Initial state, any V
ignored. To enter the Parameter Selection state, apply one V
pulse on the VOUT pin.
Parameter Selection State
parameter register containing the bit fields to be programmed. To
select a parameter register, increment through the keys by apply-
ing V
following programming parameters:

Bit Field Addressing State
individual bit fields to be programmed in the selected parameter
register (see Programming Logic table). To leave this state, either
cycle device power or blow the fuses for the selected code. Note
that merely addressing the bit field does not permanently set
the value of the selected programming parameter; fuses must be
blown to do so.
Fuse Blowing State
