Read Operation
A Read operation is initiated in the same manner as a write
operation with the exception that the R/W bit of the Slave
Address Byte is set to one.
Prior to issuing the Slave Address Byte with the R/W bit set to
one, the master must first perform a “dummy” write operation.
The master issues the start condition and the Slave Address
Byte, receives an acknowledge, then issues the Word Address
Byte. After acknowledging receipt of the Word Address Byte,
the master immediately issues another start condition and the
Slave Address Byte with the R/W bit set to one. This is followed
by an acknowledge from the device and then by the data byte
containing the register contents. The master terminates the
read operation by responding with a no-acknowledge and then
issuing a stop condition. The ninth clock cycle of the read
operation is not a “don’t care.” To terminate a read operation,
the master must either issue a stop condition during the
ninth cycle or hold SDA HIGH during the ninth clock cycle
and then issue a stop condition.
See Figure 12 for the address, acknowledge, and data
transfer sequence. See Figure 1 for bus timing.
Operational Notes
The device powers-up in the following state:
The device is in the low power standby state.
The WEL bit is set to ‘0’. It is not possible to write to the
device.
The WEL bit must be set to allow write operations.
SDA pin is the input mode.
The data in the RSR powers up in ‘0’ state.
