13. OPERATING CONDITIONS
At Device Power-Up and Power-Down
AC timing illustrated in "Figure 83. AC Timing at Device Power-Up" and "Figure 84. Power-Down Sequence" are
for the supply voltages and the control signals at device power-up and power-down. If the timing in the figures is ig-
nored, the device will not operate correctly.
During power-up and power-down, CS# needs to follow the voltage applied on VCC to keep the device not to be
selected. The CS# can be driven low when VCC reach Vcc(min.) and wait a period of tVSL.
