Programming State Machine
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 VPM pulses on the VOUT pin are ignored. To enter
the zone 1 Parameter Selection state, apply a single VPH pulse on
VOUT pin. To enter the zone 2 Parameter Selection state, apply a
sequence of three VPH pulses on the VOUT pin.
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
VPM pulses on the VOUT pin. Register keys select among the fol-
lowing programming parameters in zone 1:
1 pulse – Sens,
and the following programming parameters in zone 2:
1 pulse – VOUT(Q)
2 pulses – Coarse VOUT(Q) and LOCK
To enter the Bit Field Addressing state, send one VPH pulse on the
VOUT pin.
Note: When parameter selection for zone 1 is bypassed (by send-
ing a second VPH pulse) no register is selected, and VPM pulses
are ignored until after the VPH pulse is sent to enter zone 2.
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 VPH pulse on the VOUT
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).
