9.2.2 Power-on Precautions
♦ There is no restriction on the order of power-on/power-off between VDDL and
VDDH. However, do not supply only VDDH for more than a few seconds.
♦ Do not supply HSYNC, VSYNC and EC signals while the voltage supply is OFF.
(See the recommended input voltage in the section on absolute maximum
ratings.)
♦ After power-on, hold the S input at the ‘L’ level for at least 500 ns. Then, after
setting the S-input to the ‘H’ level, hold the XRESET input at the ‘L’ level for at
least 300 µs.
