XDS110 Debug Probe

Probe Interfaces

The XDS110 probe supports a number of interfaces for host and target communication.

2.1

Supported Communication Protocols

The XDS110 probe supports the following industry standard interfaces for host to probe and probe to
target communications:

•

Host to probe communication

–

USB 2.0 device with HS USB PHY

–

USB Communication Device Class protocol used for UART support

–

Standard USB Bulk IN and OUT endpoints support TI custom protocols

•

Probe to target communications

–

IEEE 1149.1 JTAG

–

IEEE 1149.7 cJTAG

–

ARM serial wire debug (SWD)

–

ARM serial wire output (SWO) – UART mode only

–

Transmit and receive UARTs with RS-232C signaling – no hardware handshakes

2.2

USB

Host to probe communication is accomplished through a USB link. The probe has a female micro-USB B
type connector. The probe functions as a USB device only (no host mode or OTG). Power for the XDS110
probe is sourced from the USB V

BUS

(+5 V).

2.3

Debug Interface

The XDS110 probe supports a debug connection interface through the standard CTI-20 connector (see

Section 2.3.1

). The supported debug features include:

•

5-pin 1149.1 JTAG connection (including TRSTn)

•

2-pin 1149.1 cJTAG connection

•

2-pin ARM SWD connection

•

1-pin SWO overlaid on JTAG TDO

•

Target system reset

•

Target voltage detect

•

Target disconnect detect

•

Four EMU signals for GPIO

–

2 × Probe to target

–

2 × Target to probe

–

These signals are replicated on the AUX connector because many of the debug adaptors for CTI-
20 do not support connections with GPIO.

2.3.1

Physical Connection for Debug

The CTI-20 connection is a 20-pin IDC connection using .050 by .100 inch pitch. The pin mapping is
shown in
