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 Initial state, any VPM pulses on the VOUT pin are
ignored. To enter the Parameter Selection state, apply one VPH
pulse on the VOUT pin.
Parameter Selection State
This state allows the selection of the
parameter register containing the bit fields to be programmed. To
select a parameter register, increment through the keys by apply-
ing VPM pulses on the VOUT pin. Register keys select among the
following programming parameters:
1 pulse - Sens
2 pulses - V
OUT(Q)
3 pulses - TC
SENS, POL, and LOCK
To enter the Bit Field Addressing state, apply one VPH pulse on
the VOUT pin.
Bit Field Addressing State
This state allows the selection of the
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
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 individually (see
the Fuse Blowing section).
