this is what CC2640R2F says about should down mode.
In shutdown mode, the device is turned off entirely, including the AON domain and the Sensor Controller. The I/Os are latched with the value they had before entering shutdown mode. A change of state on any I/O pin defined as a wake-up from Shutdown pin wakes up the device and functions as a reset trigger. The CPU can differentiate between a reset in this way, a reset-by-reset pin, or a power-on-reset by reading the reset status register. The only state retained in this mode is the latched I/O state and the Flash memory contents.
MCU wakes up from shutdown by changes in the I/O pins. i have a question. Bluetooth is embedded in the MCU. can Bluetooth trigger to wake MCU up upon a certain event, e.g. when Bluetooth loses proximity with a cellphone?
