    PSoC 62 Pin0[1] WCO_OUT and TRST for JTAG

    JoPa_4215136

      Hi

      In the Hardware Design Consideration of PSoC62 MCU you see that Pin0[1] is used for RTC operation and for JTAG purpose, especially for the TRST signal. I have illustrated this in a block diagram in the appendix.

       

      My questions:

      Is the signal TRST really needed for JTAG operation ?

       

      If yes, how should it be designed correctly with the RTC oscillator connected on this Pin ?

       

      In the PCB design i would put a resistor on the TRST line and if TRST is not used, i would not equip it.

       

       

      Thanks
