2222 Radio Switching Time:
23- - Start: RX_EN (LNA) pin deactivation (802.15.4 radio turning off on the end of 802.15.4 activity)
24- - End: READY pin activation for BLE operation (ble radio turned on and ready)
23+ - Start: FEM RX_EN pin event (802.15.4 radio turning off on the end of 802.15.4 activity)
24+ - End: RADIO READY event for BLE operation (ble radio turned on and ready)
2525 - Measures how quickly the radio hardware switches modes

28- - Start: First PDN event marking the end of 802.15.4 activity
29- - End: Second PDN event marking the start of BLE activity
28+ - Start: FEM PDN pin event at the end of 802.15.4 activity
29+ - End: FEM PDN pin event at the start of BLE activity
