IPMC mezzanine JTAG slave interface with FlashPro4 : JTAG signals pull up/down

Hardware

Dear support,

Reading the Hardware User Guide page , section 2.4 JTAG slave, I see that JTAG signals are directly interlinked between the FlashPro4 programmer and the CERN -IPMC mezzanine.

Do we need to put external Pull-up resistors on TDI/TMS and pull-down on TCK ?

Thanks by advance for your collaboration,

Nicolas

Hello Nicolas,

TCK has a pull-down resistor on the IPMC mezzanine, TDI and TMS have weak on-chip pull-ups, so no external resistors should be needed.

cheers,

Stefan
