PRODUCTION DATA.
The external host should drive the INT pin (GPIO3) high (whilst there is no interrupt pending) to place the device in Idle mode.
The INT pin is configured as an energysense interrupt output on the hardware-controlled device; therefore, the external host microcontroller should use it as multi-function pin. (MCU pin configured as INPUT when no requirement exists to move to standby, MCU pin as OUTPUT driving HIGH when a need exists to place the device in an idle state.)
NOTE
While the device is driving its interrupt high, any external voltage on the INT pin will be ignored by the device, until the interrupt event (and pulse) is finished.
