Help¶

Defines the size of the "down" RTT buffer (host -> target) to use for reading
commands from Tracealyzer, for RTT buffer 1 or higher.

Default buffer size for Tracealyzer is 32 bytes.

This setting is ignored for RTT buffer 0, which can't be reconfigured
in runtime and therefore hard-coded to use the defines in SEGGER_RTT_Conf.h.
