Access to Data Array
There is one index working along with two read/write windows for accessing data array.
For some hosts resending data several times while communication, it had better to put
the index P5-11 every time before read/write.
In brief, users need to set the desired read & write address by using P5-11 and then read
and write the data through P5-12 or P5-13.
For example, suppose that users want to write three consecutive numbers of data (100th,
200th, 300th), and save them into the address 11, 12, 13 of data array, the operation
steps are described as follows:
