New ContributorJTAG pin sharing in MAX10
I would like to know if I can use the option of JTAG pin sharing "on the fly" by toggle JTAG_EN pin (switch back and forth between user I/O pins and dedicated JTAG pin)?

Super ContributorHi,
Thank you for contacting Intel community.
Per Intel Max 10 pin connection guideline,
Intel suggest when to use JTAG pins as regular I/O pins, tie the JTAGEN pin to a weak 1-kΩ pull-down. To use JTAG pin as dedicated pin, tie the JTAGEN pin to a weak 10-kΩ pull-up.
