New ContributorHi,
if I enable the JTAG pin sharing for a MAX10 device, can I drive the JTAGEN pin directly by a microntroller to switch the JTAG pins from jtag function to user I/Os? Is there any problem if I connect the JTAGEN pin directly to VCCIO?
Thanks
New ContributorNo it must be tried to VCC with a pullup of 10k
Avoid using this pin if you have other pins available.
But it can be used as a regular IO.
Frequent ContributorHi ,
It is not at all recommended to connect to VCCIO

New ContributorHi,
OK, thanks.
I'll connect it to a pull-up of 10k and a pull-down of 1K by analog switch.
Frequent ContributorHi ,
That will be great, one more suggestion , if you have doubt on any pin connections, Kindly refer to the pin connection guidelines that will give you the information about all pins connections , with the above may I close the case .
