After a frame of data is sent, an interrupt will be generated. These interrupts can be masked, just like the interrupt enable control of the microcontroller. The control bit is in the config register.
Another interrupt may be generated here, that is, the number of retransmissions reaches the upper limit. If you set the retransmission to 3 times, then an interrupt will be generated if no response is received after 3 retransmissions. This can also be masked.
Let's talk about the receive mode configuration.
To be continued.
