Initial State
After system power-up, the programming logic is 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 Ini-
tial state, any V
the zone 1 Parameter Selection state, apply a single V
VOUT pin. To enter the zone 2 Parameter Selection state, apply a
sequence of three V
Parameter Selection State
This state allows the selection of the parameter register contain-
ing the bit fields to be programmed. To select a parameter register
within the chosen zone, increment through the keys by sending
V

Bit Field Addressing State
This state allows the selection of the individual bit fields to be
programmed in the selected parameter register (see the Program-
ming Logic table). To leave this state, either cycle device power
or blow the fuses for the selected code.
Note: 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
To blow an addressed bit field, apply a V
pin. Power to the device should then be cycled before additional
programming is attempted.
Note: Each bit representing a decimal code must be blown indi-
vidually (see the Fuse Blowing section).
