3.2.1
A maximum of 64 bytes can be programmed into the
block referenced by TBLPTR<21:6>. The panel that
will be written will automatically be enabled based on
the value of the Table Pointer.

Step 1: Direct access to configuration memory.
Step 2: Direct access to code memory and enable writes.
Step 3: Load write buffer for panel.
To continue writing data, repeat step 3, where the Address Pointer is incremented by 64 at each iteration of the loop.
