Notes: (5) t_NVWC is the time from the falling edge of OE or CE (whichever occurs last) of the second read cycle in the “start nonvolatile write cycle”
sequence until the self-timed, internal nonvolatile write cycle is completed.
e _{(6) Data is latched into the X84160/640/128 on the rising edge of CE or WE, whichever occurs first.}
