Table 23: Interrupt Mapping in Rx and Stby in Packet Mode
*The latter if Address filtering is enabled
Table 24: Interrupt Mapping in Tx Packet Mode
Note that depending upon the application, some uC connections may not be needed:
In addition, DATA pin (unused in packet mode) should be pulled-up to VDD through a 100 kΩ resistor.
Please refer to Table 13 for the SX1212’s pin configuration.

ADVANCED COMMUNICATIONS & SENSING
IRQ_0: if none of the relevant IRQ sources are used. In this case, leave floating.
IRQ_1: if none of the relevant IRQ sources are used. In this case, leave floating.
MISO: if no read register access is needed and the chip is used in Tx mode only. In this case, pull up to VDD
through a 100 kΩ resistor.
