• Description: 16-bit Single-chip Real Time Signal Controller
• Manufacturer: Infineon Technologies Corporation

4.6.7
The debugger can communicate with the XE164xM either via the 2-pin DAP interface or
via the standard JTAG interface.
Debug via JTAG
The following parameters are applicable for communication through the JTAG debug
interface. The JTAG module is fully compliant with IEEE1149.1-2000.
Note: These parameters are not subject to production test but verified by design and/or
Note: Operating Conditions apply.

1) Under typical conditions, the JTAG interface can operate at transfer rates up to 20 MHz.
2) The falling edge on TCK is used to generate the TDO timing.
3) The setup time for TDO is given implicitly by the TCK cycle time.
