POWER UP INITIALIZATION
IS66WV1M16EALL and IS66/67WV1M16EBLL include an on-chip voltage sensor used to launch the power-up
initialization process. When VDD reaches a stable level at or above the VDD (min) the device will require 50μs
to complete its self-initialization process. During the initialization period, CS1# should remain HIGH. When initialize-
ation is complete, the device is ready for normal operation.
