When the program ROM area is specified while a program or block erase operation to the data flash, array data
can be read. This eliminates the need for writing software commands. Access time is the same as for normal
read operations.
Any other block of the data flash cannot read during a program or block erase operation to the data flash.
Figure 30.6 shows the BGO Function.
