Read anytime. Write in special modes only (SMODN = 0). These bits are
used for test purposes only. In normal modes the bits are forced to zero.
EEODD â Odd Row Programming
0 = Odd row bulk programming/erasing is disabled.
1 = Bulk program/erase all odd rows.
EEVEN â Even Row Programming
0 = Even row bulk programming/erasing is disabled.
1 = Bulk program/erase all even rows.
MARG â Program and Erase Voltage Margin Test Enable
0 = Normal operation.
1 = Program and Erase Margin test.
This bit is used to evaluate the program/erase voltage margin.
EECPD â Charge Pump Disable
0 = Charge pump is turned on during program/erase.
1 = Disable charge pump.
EECPRD â Charge Pump Ramp Disable
Known to enhance write/erase endurance of EEPROM cells.
0 = Charge pump is turned on progressively during program/erase.
1 = Disable charge pump controlled ramp up.
EECPM â Charge Pump Monitor Enable
0 = Normal operation.
1 = Output the charge pump voltage on the IRQ/VPP pin.
