1. Advance automatic RF shutdown

2. Terminate on RX functions
Posible to terminate on three (3) individual criteria
RSSI below threshold
Preamble quality not reached
Sync word is incorrect
To test this we created a test case where the system would exercise all three events in sequence
Measured data (including startup, capacitor charge effects, other board issues…)

3. No RF signal found (RSSI failed)
In this example the TX did not send a packet
The RX discovers that the RSSI threshold has not been exeeded.
Terminates in a programmable timeout, this case 200us.
This provides a very low average current of 86uA at 10 times a second
Green = CC112x current
Pink = TX Sync
Cyan = RX Sync
Blue = RX idle

4. Bad Preamble Quality
In this example the TX did send a packet, but at an incorrect bit rate.
The RX discovers that RSSI is OK
But then discovers that the RF energy is not a preamble of expected data rate, etc...
This provides a low average current of 300uA at 10 times a second
Green = CC112x current
Pink = TX Sync
Cyan = RX Sync
Blue = RX idle

5. Bad Sync word
In this example the TX did send a packet, but with an incorrect syncword
The RX discovers that RSSI is OK
RX preamble is OK
But Sync word is NOT OK and stops
This provides a low average current of 430uA at 10 times a second
Green = CC112x current
Pink = TX Sync
Cyan = RX Sync
Blue = RX idle

6. Good data burst, passed all checks
In this example the TX did sent good packet
The RX discovers that RSSI is OK
RX preamble is OK
Sync word is OK
Continues to recieve the entire packet
This provides a low average current of 3mA at 10 times a second
Green = CC112x current
Pink = TX Sync
Cyan = RX Sync
Blue = RX idle
