Reading a Single Byte from a Slave: Unlike the write
operation that uses the memory address byte to define
where the data is to be written, the read operation occurs
at the present value of the memory address counter. To
read a single byte from the slave, the master generates a
START condition, writes the slave address byte with R/W
= 1, reads the data byte with a NACK to indicate the end
of the transfer, and generates a STOP condition.

PON Triplexer Control and
Manipulating the Address Counter for Reads: A
dummy write cycle can be used to force the address
pointer to a particular value. To do this, the master gen-
erates a START condition, writes the slave address byte
(R/W = 0), writes the memory address where it desires to
read, generates a repeated START condition, writes the
slave address byte (R/W = 1), reads data with ACK or
NACK as applicable, and generates a STOP condition.
