Device Access Port (DAP / DAP2) with up to 160 MHz serial clock support

The 2-pin and 3-pin Device Access Ports (DAP) as well as a 3-pin DAP2 was established by Infineon, for the TriCore™ AUDO Future, AUDO MAX, and AURIX devices, as well as for other upcoming 16-bit and 32-bit microcontrollers. The Device Access Port DAP/DAP2 allows debug communication with higher transmission rates than existing JTAG based communication channels up to 160 MHz. The block transfer rate of the DAP2 could be increased almost three-fold to 30 MByte/s by means of an optimized protocol.

DAP, DAP2, Single-pin DAP via CAN (SPD) and DAP over CAN Physical Layer (DXCPL) are supported by the Universal Access Devices (UAD2pro / UAD2nextUAD3+).
