Power Modes

When the supply to VCCIO and VCC is applied, the internal regulator is powered by VCC. An internal POR

pulse will be generated during the regulator power up until it is stable. After the initial power up, the

FT81x will stay in the SLEEP state. When needed, the host can set the FT81x to the ACTIVE state by

performing a SPI ACTIVE command. The graphics engine, the audio engine and the touch engine are only

functional in the ACTIVE state. To save power the host can send a command to put the FT81x into any of

the low power modes: STANDBY, SLEEP and POWERDOWN. In addition, the host is allowed to put the

FT81x in POWERDOWN mode by driving the PD_N pin to low, regardless of what state it is currently in.

Refer to

Figure 4-11 for the power state transitions.
