DAP Support for Infineons TriCore and XC2000<br />
The Device Access Port DAP, a new debug interface was established by Infineon for the AUDO<br />
Future,<br />
XC2000M, XE166M devices and other upcoming 16-bit and 32-bit-microcontrollers. The 2-wire or<br />
3-wire<br />
DAP allows debug communication with higher transmission rates than existing JTAG based<br />
communication channels. The new board connector is a 0.05 inch double row 10-pins microterminal<br />
with keying shroud, which saves board space on targets system side.<br />
UDE Support for DAP<br />
High-speed downloading via DAP is achieved by the communication devices UAD2 and UAD2+, the<br />
hardware addons of the Universal Debug Engine.<br />
<br />
<br />
<br />
<br />
<br />
DAP communication frequency @ 50 MHz<br />
Transfer rate up to 3,5 MByte/s ( with TC1797 AUDO Future)<br />
2-wire/pin and 3-wire/pin DAP mode supported<br />
Prepared for single-wire/pin DAP mode<br />

UAD DAP Extender with LVDS<br />
The UAD2+ with DAP Extender uses the LVDS technology and a galvanically isolated interface for<br />
highest<br />
performance and signal integrity of the DAP interface. It allows interface cable length of up to 2<br />
meters<br />
SWD Support for Cortex<br />
The Serial Wire Debug (SWD) interface or Serial Wire Debug Port (SW-DP) is one of the features of<br />
the debug and trace technology ARM CoreSight. First implementations of SWD are realized in the<br />
derivatives of the Cortex-M3 core Stellaris of Luminary Micro (now Texas Instruments) and in the<br />
derivatives of the STM32 family by STMicroelectronics. The known JTAG Debug Port (JTAG-DP) is<br />
supported furthermore. Both debug ports, the SWD and the alternative JTAG debug port can be<br />
combined to the Serial Wire JTAG Debug Port (SWJ-DP), the CoreSight standard port.<br />
When using SWD, the TDO signal can provide trace event messages via the Serial Wire Output<br />
(SWO). This behaviour can be used by the Serial Wire Viewer (SWV) to output system events via a<br />
single pin:<br />

UDE Support for SWD<br />
Target connection via SWD is achieved by the communication devices UAD2 and UAD2+, the<br />
hardware add-ons of the Universal Debug Engine and the additional UAD2 SWD adapter.<br />
UAD SWD Extender with LVDS<br />
The UAD2+ in touch with the Extender and the SWD adaptor uses the LVDS technology and a<br />
galvanically isolated interface for highest performance and signal integrity of the SWD interface. It<br />
allows interface cable length of up to 2 meters.<br />
