RN4870/71
9.0 TIMING CHARACTERISTICS
Figure 9-1 shows the timing diagram for the RN4870/
71 module when it is reset in the Test mode and Appli-
cation mode. Figure 9-2 shows the timing diagram for
the module when it is powered on. In Application mode,
when RN4870/71 is ready to talk to the MCU after
Reset, the module provides a UART response indicat-
ing that the Reset is complete. For more details, refer
to the “RN4870/71 Bluetooth
