Description
Leave unconnected
UART Serial In
Note: used for debugging and SW download purposes only
Main supply voltage.
Must be connected to battery/supply terminal and ULE_VBAT
(3.3V) at F6.
Recommendation: place header option to connect VBAT (B10)
with VBATSW (A9) to bypass sleep mode for debugging purposes
Ground
Leave unconnected (RF test pad)
High power GPIO driver
Used to measure tuned XTAL frequency if needed in debugging.
Recommendation: connect test point for probe
Leave unconnected
Leave unconnected
UART Serial Out
Note: used for debugging and SW download purposes only
JTAG-SDI+; one wire Debug interface with open-drain.
Note: used for debugging and SW download purposes only
Switched battery voltage.
Equal to battery voltage when in active state.
Must be connected to VBATuC (3.3V) at A9.
Optional connection to VDDPA at E1 (high output current ports
supply).
High power GPIO driver
Power on, Switches on the device if Voltage > 1.5V (in active state).
Recommendation: connect test point for debugging
Leave unconnected
