Table 11. SDA Bit Definitions and Descriptions
Bit
Description
S
Start condition.
P
Stop condition.
A
Acknowledge.
AD0, AD1
Package pin-programmable address bits.
X
Don’t care.
W
Write.
R
Read.
2T
Second fuse link array for two-time programming. Logic 0 corresponds to first trim. Logic 1 corresponds to
second trim. Note that blowing Trim 2 before Trim 1 effectively disables Trim 1 and, in turn, allows only one-time
programming.
SD
Shutdown connects wiper to Terminal B and open circuits Terminal A. It does not change the contents of the wiper register.
T
OTP programming bit. Logic 1 permanently programs the wiper.
OW
Overwrite the fuse setting and program the digital potentiometer to a different setting. Note that upon power-up,
the digital potentiometer presets to either midscale or fuse setting, depending on whether the fuse link is blown.
D7, D6, D5, D4, D3,
D2, D1, and D0
Data bits.
E1, E0
OTP validation bits:
0, 0 = ready to program.
1, 0 = fatal error. Some fuses are not blown. Do not retry. Discard this unit.
1, 1 = programmed successfully. No further adjustments are possible.
