Command-Byte and Data-Byte
Programming
The devices are programmed with a command byte and
a data byte or data word (2 bytes). Each bit of the
command byte selects one of the functional blocks to be
controlled by the subsequent data byte (word). The data
byte (word) sets the state of the selected block(s). For
the three switch-matrix blocks, the data byte sets the
switch state. For the bias-resistor block, the data word
controls which bias network is active (see
Functional
Diagram).
A logic “1” in any bit position of the data byte makes
that function active, while a logic “0” makes it inactive.
Tables 1–4 describe the command byte and the corre-
sponding data byte. If more than one bit of the com-
mand byte is set, the data byte programs all of the
corresponding blocks. This operation is useful, for
instance, to simultaneously set all switch matrices to
