Unprotected Read
The Unprotected Read function reads 8 bit values from any area of the I/O database. Access
to the I/O database is limited to the unprotected address range.
Any number of bytes may be read up to the maximum number. The read may start at any
byte address, provided the entire block is within the unprotected address range.
