XC2000 Family / Compact Line
Electrical Parameters
4.7.6 Debug Interface Timing
The debugger can communicate with the XC2220U via 1-pin SPD interface, via the 2-
pin DAP interface or via the standard JTAG interface.
Debug via DAP
The following parameters are applicable for communication through the DAP debug
interface.
Note: These parameters are not subject to production test but verified by design and/or
characterization.
Note: Operating Conditions apply.
Table 36 is valid under the following conditions: C_L= 20 pF; voltage_range= upper

1) The debug interface cannot operate faster than the overall system, therefore t₁₁ ≥ t_SYS.
2) The Host has to find a suitable sampling point by analyzing the sync telegram response.
