Try Mode In Try mode, bit field addressing is accomplished by
applying a series of V
PM
pulses to the VCC pin of the device, as
shown in figure 6. Each pulse increases the bit field value for the
selected parameter, increasing by one on the falling edge of each
additional V
PM
pulse. When addressing the bit field in Try mode,
the quantity of V
PM
pulses is represented by a decimal number
called the code. Addressing activates the corresponding fuse
locations in the given bit field by increasing the binary value of
an internal DAC, up to the maximum possible code. As the value
of the bit field code increases, the value of the programmable
parameter changes. Measurements can be taken after each V
PM
pulse to determine if the required result for the programmable
parameter has been reached. Cycling the supply voltage resets
all the locations in the bit field that have un-blown fuses to their
initial states.
When setting the B
OP
Trim parameter, as an aid to programming,
values can be traversed from low to high, or from high to low. To
accommodate this direction selection, the value of the bit field
(and code) defaults to the value 1, on the falling edge of the final
register selection V
PH
pulse (see figure 5). A complete example is
provided in figure 11.
Blow Mode After the required code is determined for a given
parameter, its value can be set permanently by blowing individual
fuses in the appropriate register bit field. Blowing is accom-
plished by selecting the register, then the Blow mode selection
key, followed by the appropriate bit field address, and ending
the sequence with the Blow pulse. The Blow mode selection key
is a sequence of nine V
PM
pulses followed by one V
PH
pulse. A
complete example is provided in figure 12.
The Blow pulse consists of a V
PH
pulse of sufficient duration,
t
BLOW
, to permanently set an addressed bit by blowing a fuse
internal to the device. Due to power requirements, the fuse for
each bit in the bit field must be blown individually. The A119x
family built-in circuitry allows only one fuse at a time to be
blown. During Blow mode, the bit field can be considered a one-
hot shift register. Table 3 relates the quantity of V
PM
pulses to
the binary and decimal values for Blow mode bit field address-
ing. It should be noted that the simple relationship between the
quantity of V
PM
pulses and the corresponding code is:
2
n
= Code,
where n is the quantity of V
PM
pulses. The bit field has an initial
state of decimal code 0 (binary 000000).
