ADG2188
Rev. 0 | Page 22 of 28
WRITE OPERATION
When writing to the ADG2188, the user must begin with an
address byte and R/W bit, after which the switch acknowledges
that it is prepared to receive data by pulling SDA low. This
address byte is followed by the two 8-bit words. The write
operations for the switch array are shown in Figure 34. Note
that it is only the condition of the switch corresponding to the
bits in the data bytes that changes state. All other switches retain
their previous condition.
READ OPERATION
Readback on the ADG2188 is designed to work as a tool for
debug and can be used to output the status of any of the
64 switches of the device. The readback function is a two-step
sequence that works as follows:
1.
Select the relevant X line to be read back from. Note that
there are eight switches connecting that X line to the eight
Y lines. The next step involves writing to the ADG2188 to
tell the part to reveal the status of those eight switches.
a.
Enter the I2C address of the ADG2188, and set the
R/W to 0 to indicate a write to the device.
b.
Enter the readback address for the X line of interest,
the addresses of which are shown in Table 8. Note that
the ADG2188 is expecting a 2-byte write; therefore, be
sure to also enter another byte of don’t cares (see
c.
The ADG2188 then places the status of those eight
switches in a register than can be read back.
2.
The second step involves reading back from the register
that holds the status of the eight switches associated with
the X line of choice.
a.
As before, enter the I2C address of the ADG2188. This
time, set the R/W to 1 to indicate a read back from the
device.
d.
As with a write to the device, the ADG2188 outputs a
2-byte sequence during readback. Therefore, the first
eight bits of data out that are read back are all 0s. The
next eight bits of data that come back are the status of
the eight Y lines attached to that particular X line. If
the bit is a 1, then the switch is closed (on); similarly, if
the bit is a 0, the switch is open (off).
The entire read sequence is shown in Figure 35.
