Page 24: Jtag
................. . A JTAG interface is available both for debug purposes and during application development using the Digi JTAG Link debugger. Because the module has only 48 pins, the JTAG interface is multiplexed with address lines ADDR[5...9]. The voltage level on pin LEDLNK/SEL# controls the multiplexing. -
Page 25: Debugging Notes
The debugger must be configured to have open drain characteristics as its SRST# output. The module has a pullup resistor of 5K. If you want to use a debugger not provided by Digi, contact Digi technical support (www.digiembedded.com/support) to ensure that the debugger is supported. -
