NOTES
1 See DC Characteristics for value of VPPH The VPP
power supply can be hard-wired to the device or
switchable When VPP is switched VPPL may be
ground no-connect with a resistor tied to ground or as
defined in Characteristics Section Refer to Principles
of Operation
2 Program Verify is only performed after byte program-
ming A final read compare may be performed (option-
al) after the register is written with the Read command
3 CAUTION The algorithm MUST BE FOLLOWED
to ensure proper and reliable operation of the de-
vice
