Power Button Configuration Register

The Power Button Configuration Register controls the length of time that the designated power button must indicate a

touch before an interrupt is generated and the power status indicator is set (see Section 4.5, "Power Button").

Bit 6 - STBY_PWR_EN - Enables the power button feature in the Standby state.

• ‘0’ (default) - The Standby power button circuitry is disabled.

• ‘1’ - The Standby power button circuitry is enabled.

Bits 5 - 4 - STBY_PWR_TIME[1:0] - Determines the overall time, as shown in Table 5-47, that the power button must

be held in the Standby state, in order for an interrupt to be generated and the PWR bit to be set.

Bit 2 - PWR_EN - Enables the power button feature in the Active state.

• ‘0’ (default) - The power button circuitry is disabled in the Active state.

• ‘1’ -The power button circuitry is enabled in the Active state.

Bits 1 - 0 - PWR_TIME[1:0] - Determines the overall time, as shown in Table 5-47, that the power button must be held

in the Active state, in order for an interrupt to be generated and the PWR bit to be set.
