This command is a special case of the High Voltage
Decrement Wiper
commands to the non-volatile memory locations 02h,
03h, and 0Fh. This command is used to enable or
disable either the software Write Protect, wiper 0
WiperLock Technology, or wiper 1 WiperLock Technol-
ogy.

A Modify Write Protect or WiperLock Technology
Command will only start an EEPROM write cycle (t

CS pin to the active state (V
During an EEPROM write cycle, only serial commands
to Volatile memory (addresses 00h, 01h, 04h, and 05h)
are accepted. All other serial commands are ignored
until the EEPROM write cycle (t
allows the Host Controller to operate on the Volatile
Wiper registers and the TCON register, and to Read
the Status Register. The EEWA bit in the Status register
indicates the status of an EEPROM Write Cycle.
