4.10 External Static Wake for Software Development

Having HW-based wake-up capability is recommended while developing user Flash software for the transceiver, transmitter or receiver. After connecting the Voltage Supply (VS), the devices stay in the OFF mode, waiting for a wake event from an external source. It can be difficult to implement a static wake function to the host controller. Therefore, it can be helpful to have a jumper or something similar, to keep the device awake all the time. This can help in achieving a suitable operation in ISP mode. Between the ISP steps, the NRESET line releases and the device enters the OFF mode and requires a wake prior to the start of the next ISP operation.
