- * NOTE:
- * Tested the following to see what would happen:

- * -> Set up nrf to receive. Clear ADDRESS event register.
- * -> Enable ADDRESS interrupt on nrf5 by writing to INTENSET.
- * -> Enable RX.
- * -> Disable interrupts globally using OS_ENTER_CRITICAL().
- * -> Wait until a packet is received and the ADDRESS event occurs.
- * -> Call ble_phy_disable().
- *
- * At this point I wanted to see the state of the cortex NVIC. The IRQ
- * pending bit was TRUE for the radio interrupt (as expected) as we never
- * serviced the radio interrupt (interrupts were disabled).
- *
- * What was unexpected was this: without clearing the pending IRQ in the NVIC,
- * when radio interrupts were re-enabled (address event bit in INTENSET set to
- * 1) and the radio ADDRESS event register read 1 (it was never cleared after
- * the first address event), the radio did not enter the ISR! I would have
- * expected that if the following were true, an interrupt would occur:
- * -> NVIC ISER bit set to TRUE
- * -> NVIC ISPR bit reads TRUE, meaning interrupt is pending.
- * -> Radio peripheral interrupts are enabled for some event (or events).
- * -> Corresponding event register(s) in radio peripheral read 1.
- *
- * Not sure what the end result of all this is. We will clear the pending
- * bit in the NVIC just to be sure when we disable the PHY.
