Step 1: Load 3C0004h to Address Pointer.
Step 2: Erase boot block.
Step 3: Erase Panel 1.
Step 4: Configure device for single panel write.
Step 5: Direct access to code memory.
Step 6: Set the Table Pointer to point to the first 64-byte block of Panel 2.
Step 7: Enable memory writes and setup an erase.
Step 8: Perform Data EEPROM unlock sequence.
Step 9: Initiate erase.
Step 10: Wait for P11+P10 and then disable writes.
Step 11: Increment Table Pointer by 64 and repeat from step 7 to step 10, 40 times.
