Application Information
28.5
Connection of P0.2 for SWD debug mode
To enter the SWD debug mode, P0.2 needs to be 0 at the rising edge of the reset signal.
P0.2 has an internal pulldown, so it just needs to be ensured that there is no external 1 at P0.2 when the debug
mode is entered.
28.6
Connection of TMS
For the debug mode, the TMS pin needs to be 1 at the rising edge of the reset signal. This is controlled by the
debugger. The TMS pin has an internal PD.
To avoid the device entering the debug mode unintendedly in the final application, adding an external pull-
down additionally is recommended.
28.7
ESD Immunity According to IEC61000-4-2
Note:
Tests for ESD robustness according to IEC61000-4-2 “gun test” (150pF, 330
Ω
) were performed. The
results and test condition are available in a test report. The achieved values for the test are listed in
below.
