[Solved]Does a RADIO shorts still set events for states that are bypassed?

[butch]

For the radio peripheral, if I use a shorts (shortcut) from END to DISABLED states, is EVENT_END still set? Because I enable an interrupt on EVENT_END, but not on EVENT_DISABLED. And the interrupt never seems triggered.

My mental model is that both EVENT_END and EVENT_DISABLED would be set. I don't deeply understand how the shortcut works, whether it uses the PPI? My mental model is that shortcuts are internal to the radio peripheral.

(I am writing a broadcast, datagram, wireless protocol stack, open sourced at GitHub nrf5rawProtocol.)

My problem was I was not enabling IRQ from radio in NVIC. To get the interrupt to work you need 1)enable IRQ in the Radio 2) enable IRQ in NVIC 3)enable IRQ in the PRIMASK. IMO the NVIC should be better documented in Nordic documenation, not just ARM documentation. Is it a peripheral or isn't it?
