4.8.3.6 Pin Status at Different Power States

The FT801 pin status depends on the power state of the chip. See the following table for more details. At

power transition from ACTIVE to STANDBY or ACTIVE to SLEEP, all pins retains their previous status. The

software needs to set AUDIO_L, BACKLIGHT and PCLK to a known state before issuing power transition

commands.
