J-LINK SWDIO

Hello Dialog Forum. Have a question. Does the DA14580 SWDIO pin require a pull-up resistor when attached to the J-link SWDIO line? The J-Link documentation states that one is required and that ARM recommends a 100K pull-up. Please see the "J-Link / J-Trace (UM08001)" documentation at segger.com (page 347, table 12.3). I've got it working without this pull-up, but want to make sure I won't run into stability issues without this pull-up.

Thanks much,

Alex
