JTAG/SWD interface characteristics

Unless otherwise specified, the parameters given in Table 115 and Table 116 for JTAG/SWD

are derived from tests performed under the ambient temperature, frcc_c_ck frequency and

VDD supply voltage summarized in Table 13: 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: 0.5×VDD

Refer to Section 6.3.17: I/O port characteristics for more details on the input/output

characteristics.
