1 The conditions of the current measurements for all different drives are as follows:

IOL: at 0.4 V

IOH: at VDDIO * 0.8 V

Maximum corner for 3.3 V mode: 3.6 V, -40

°C, fast process.

Minimum corner for 3.3 V mode: 3.0 V, 105

°C, slow process

8 gpio pins (LCD_D0-D7) and 2 gpio_clk pins (LCD_DOTCLK and LCD_WR_RWN) simultaneously loaded.

2 See the i.MX28 reference manual for detailed pull-up configuration of each I/O.
