8.5 Debug and bridge performance
Table 14 gives an overview of the achievable maximal performances with
STLINK-V3PWR on different
communication channels. Those performances are also depending on the overall system context (target
included), so they are not guaranteed to be always reachable. For instance, a noisy environment or connection
quality can impact system performance.
