PON Triplexer Control and

Monitoring Circuit

____________________________________________________________________

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.

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.
