... NXP Semiconductors Standby mode is signalled by a LOW-level on pin RXD which can be used as an interrupt for the microcontroller. In Standby mode (pin SLP_N is still LOW), the condition of pin TXD (weak pull-down or strong pull-down) indicates the wake-up source: weak pull-down for a remote wake-up request and strong pull-down for a local wake-up request. ...
