Figure 9 shows a typical application schematic.
Short Jumper JP1-1 if it is desired to supply the target board from the Debug Adapter (50mA
max). Connect the bottom exposed pad of the AX8052F100 to ground.
If the debugger is not running, PB6 and PB7 are not driven by the Debug Adapter. If the debugger
is running, the PB6 and PB7 values the software reads may be set using the Pin Emulation feature
of the debugger.
PB3 is driven by the debugger only to bring the AX8052F100 out of Deep Sleep. It is high
impedance otherwise.
Port Pins PR0—PR5 may be used to connect an AXSEM Radio Chip, or as General Purpose I/O.
Crystals are optional. Crystal Load Capacitances should be chosen according to the Crystal
Datasheet.
