Name and Function
WE#
INPUT
WRITE ENABLE:
Controls writes to the CUI and array blocks. Addresses and data
are latched on the rising edge of the WE# pulse.
RY/BY#
OUTPUT
READY/BUSY#:
Indicates the status of the internal WSM. When low, the WSM is
performing an internal operation (block erase, program, or lock-bit configuration).
RY/BY#-high indicates that the WSM is ready for new commands, block erase or
program is suspended, or the device is in deep power-down mode. RY/BY# is
always active.
