EECPD — Charge Pump Disable
EECPRD — Charge Pump Ramp Disable
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.
This bit is used to evaluate the program/erase voltage margin.
Known to enhance write/erase endurance of EEPROM cells.
