The general format of the read command is shown in

Figure 15.

First part of the general read command consists of writing an address to the Index Register

of the POE controller. If the Index Register already contains the address of the register to be

read, as the result of a previous read or write command, then it is not necessary to write that

address to the Index Register again.

After each byte is read from the POE controller, the Index Register is required to increment

by one.

A read command can contain from 0 to 255 bytes.
