This bit is used to evaluate the program/erase voltage margin.
Known to enhance write/erase endurance of EEPROM cells.
For More Information On This Product,
0 = Odd row bulk programming/erasing is disabled.
1 = Bulk program/erase all odd rows.
0 = Even row bulk programming/erasing is disabled.
1 = Bulk program/erase all even rows.
0 = Normal operation.
1 = Program and Erase Margin test.
0 = Charge pump is turned on during program/erase.
1 = Disable charge pump.
0 = Charge pump is turned on progressively during program/erase.
1 = Disable charge pump controlled ramp up.
0 = Normal operation.
1 = Output the charge pump voltage on the IRQ/V
