When RY/BY#= V
ready to accept read operations and
commands. When RY/BY#= V
the device is either executing an em-
bedded algorithm or the device is
executing a hardware reset opera-
tion.
Write Protect/Acceleration Input.
When WP/ACC#= V
and lowest two 4K-word sectors are
write protected regardless of other
sector protection configurations.
When WP/ACC#= V

PPB is programmed. When
WP/ACC#= 12V, program and erase
operations are accelerated.
