The mid voltage range, V
PM
, is a neutral level used to separate
V
PH
and V
PL
pulses from each other.
The low level, V
PL
, pulse is used to increment the mode, register,
and bitfield addresses that are to be set. The device generates a
V
PL
pulse on the falling edge of the mid-level to low-level transi-
tion, V
PM
to V
PL
.
In Try Value mode,the programming drive signal can be held
at 5 V or less if no code search is required. If a code search is
required, then the output drive signal must be released to allow
the output level to be read for each bitfield increment (see panels
A and B, below).
To guarantee proper pulse recognition, each level must be held
for the predefined durations specified in the Programming Proto-
col Characteristics table. Failure to follow the specifications may
produce undefined results. Examples of common pulse trains are
shown in panels C and D, below.
A. Try Value Mode. Code search with drive signal held
at 5 V.
B. Try Value Mode. Code search with drive signal released
after each V
PM
, allows output to be measured after each code
increment.
C. Blow Fuse Mode: Code 8 / bit 4 is programmed.
D. Lock Device Mode. Device-level Lock Bit is programmed;
device programming is then permanently disabled.
