MAX10 JTAGEN connections

Hi,

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

No 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.

Hi , 

It is not at all recommended to connect to VCCIO

Hi,

OK, thanks.

I'll connect it to a pull-up of 10k and a pull-down of 1K by analog switch.

Hi ,

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 .
