Hello all, I'm working on a small project which consists of CC1120 interfaced with a microcontroller. During initialization, I've configured all ports of the microcontroller as output and pulled them low. After system initialization, initialize the pins related to CC1120 (setting MISO, GPIOs, etc. as input), and assert the RESET pin of CC1120 (pull it high).
Now, till this RESET pin is not asserted, the overall current consumption of the system is too high. The current is nearly about 100-110mA, whereas just after the initialization, it drops to 20-30mA (which is the normal expected current consumption).
Could you kindly identify what might be happening? Is this normal behaviour for CC1120?
