Power management

The STMPE1208S operates in 3 states.

Figure 4.

STMPE1208S operating states

On RESET, the STMPE1208S enters the ACTIVE state immediately.

Upon a fixed period of inactivity, the device enters into the SLEEP state. Any touch activity in

SLEEP state would cause the device to go back to ACTIVE state.

In SLEEP mode:

-Calibration continues if F2A bit is set in CONTROL register

-Calibration stops if F2A bit is NOT set in CONTROL register

If no touch activity is expected, the host may set the device into HIBERNATE state to save

power.
