XTend Digimesh API mode question

I’ve been reading the docs on the Xtend Module. We will be using a number of these in digimesh and using API mode for transmission. I’m a bit confused by the definition of the RX Receive packet API (0x80).

In the docs it lists an “Options” byte (14) with 2 bits that can be set. The first bit just says “ACK” and the 2nd bit says “Indicate Broadcast”. What do these mean to me if I’m writing the code to handle these commands?

it is telling you if t packet you are recieving was addressed to that unit or if it was broadcasted and your device is one of several radios that catched it.
