    About recommended pin processing of debug pins (SWDCK, SWDIO, XRES)

    harukawa.nr_3407421

      Hellow,

       

      The following SWD interface is used to use the debugging function of CY8C4024LQI-S411.

       

      SWDCK (P3_3 pin)

      SWDIO (P3_2 pin)

      XRES

       

      Q1.

      Could you provide me with the recommended pin processing information for these debug pins?

       

      *

      For example, the following information:

      1)The pull-up resistors of SWDIO and SWDCK must be in the range of 1 k to 100 k ohms

      2)XRES does not require pull-up processing

       

      Best regards,
