3.10
The procedure for reading data EEPROM memory is
the same as reading the code memory. The only differ-
ence is that the 16-bit data words are read instead of
the 24-bit words.

Step 1: Exit Reset vector.
Step 2: Initialize TBLPAG and the Read Pointer (W6) for TBLRD instruction.
Step 3: Initialize the Write Pointer (W7) to point to the VISI register.
Step 4: Read and clock out the contents of the next location of data EEPROM memory through the VISI register
Step 5: Repeat Step 4 until the required data EEPROM memory is read.
Step 6: Reset device internal PC.
