Locks out access to all registers except Fuse Check
Code. The number used to identify the combination of fuses
activated in a bit field, expressed as the decimal equivalent of the
binary value. The LSB of a bit field is denoted as code 1, or bit 0.
Addressing. Setting the bit field code in a selected register by
serially applying a pulse train through the VCC pin of the device.
Each parameter can be measured during the addressing process,
but the internal fuses must be blown before the programming
code (and parameter value) becomes permanent.
Fuse Blowing. Applying a V
PH
pulse of sufficient duration to
permanently set an addressed bit by blowing a fuse internal to the
device. Once a bit (fuse) has been blown, it cannot be reset.
Blow Pulse. A V
PH
pulse of sufficient duration to blow the
addressed fuse.
Cycling the Supply. Powering-down, and then powering-up the
supply voltage. Cycling the supply is used to clear the program-
ming settings in Try mode.
Programming Procedure
Programming involves selection of a register, a mode, and then
setting values for parameters in the register for evaluation or for
fuse blowing. Figure 10 provides an overview state diagram.
Register Selection Each programmable parameter can be
accessed through a specific register. To select a register, a
sequence of voltage pulses consisting of a V
PH
pulse, a series of
V
PM
pulses, and a V
PH
pulse (with no V
CC
supply interruptions)
must be applied serially to the VCC pin. The quantity of V
PM
pulses is called the key, and uniquely identifies each register. The
pulses for selection of register key 1, is shown in figure 5. No
V
PM
pulse is sent for key 0. The register selections are shown in
table 2.
Mode Selection After register selection, the mode is selected,
either Try or Blow mode. Try mode is selected by default. To
select Blow mode, that mode selection key must be sent.
