JTAG/SWD interface characteristics
Unless otherwise specified, the parameters given in Table 116 and Table 117 for JTAG/SWD
are derived from tests performed under the ambient temperature, frcc_c_ck frequency and
VDD supply voltage summarized in Table 23: General operating conditions, with the
following configuration:
•
Output speed is set to OSPEEDRy[1:0] = 0x10
•
Capacitive load C=30 pF
•
Measurement points are done at CMOS levels: 0.5VDD
Refer to Section 6.3.15: I/O port characteristics for more details on the input/output
characteristics.
