4.8.3.6 Pin Status at Different Power States

The FT800 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 retain their previous status. The software needs to set AUDIO_L, BACKLIGHT and

PCLK to a known state before issuing power transition commands.
