Dear Freescale TIC,
I would like to maintain pins of LCDIF in the Low state until the power supply of a LCD module is stabilized.
Are the following pins in a Low state after Reset and during Reset?
・LCD_DATA[17..0」
・LCD_VSYNC
・LCD_HSYNC
・LCD_CLK
・LCD_ENABLE
Best Regards,

From section 8.1 (Pin Descriptions Overview) of the i.MX28 Reference Manual :
"Almost all digital pins are powered down (that is, high impedance)
or configured as GPIO input at reset, until reprogrammed. The only
exceptions are TEST PINS(TESTMODE, DEBUG, JTAG pins). These pins
are always active."
