Stop Separated Reads:
A further form of read is available which is, in effect, an extension of the combined format
read. This format allows a master to set up the register address pointer for a read, and return to that slave some
time later to read the data. After a start condition, the slave address is sent, followed by a write. The SC614 then
acknowledges that it is being addressed, and the master responds with the 8-bit target register address. The
master then sends a stop or repeated start condition, and may address another slave. Some time later the master
sends a start or repeated start condition, and a valid slave address is sent, followed by a read. The SC614 then
acknowledges and returns the data at the register address location that had previously been set up.
