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 MCU after Reset,
the module provides a UART response indicating
that the Reset is complete. For more details, refer to the
“RN4870/71 Bluetooth
®
Low Energy Module User's
Guide” (DS50002466).
