... When the CAT5132 READ mode it transmits 8 bits of data, releases the SDA line, and monitors the line for an acknowledge. Once it receives this acknowledge, the CAT5132 will continue to transmit data acknowledge is sent by the Master, the device terminates data transmission and waits for a STOP condition ...

... WCR (80h (00h) is being addressed (see Figure 5). Slave Address Instruction Byte Description The first byte sent to the CAT5132 from the master processor is called the Slave/DPP Address Byte. The most significant five bits of the slave address are a device type identifier. For the CAT5132 these bits are fixed at 01010 (refer to Table 2) ...

... An increment operation (see Table 4) requires a Start condition, followed by a valid increment address byte (01011), a valid address byte 00h. After each of the two bytes, the CAT5132 responds with an acknowledge. At this time if the data is high then the wiper is incremented or if the data is low the wiper is decremented at each clock. Once the stop is issued then the device enters its standby state with the WCR data as being the last inc/dec position ...

... A read operation (see Table 7) requires a Start condition, followed by a valid slave address byte, a valid address byte 00h, a second Start and a second slave address byte for read. After each of the three bytes the CAT5132 responds with an acknowledge and then the device transmits the data byte. The master terminates the read operation by issuing a STOP condition following the last bit of Data byte ...
