Data Emulation Memory
The BR_XETK-S3.0 uses a portion of or up to the entire size of the ED RAM, to
emulate data in internal flash. The following table lists the supported microcon
-
trollers, the size of the ED RAM, and states if the ED RAM is capable of being
powered using a standby supply.
The ED RAM is also used to support other functionalities which reduces the
amount of ED RAM available for data emulation. E.g., the page switch mail box
and OMD requires typically one tile of ED RAM (64 KB for TC2xx-ED, 256 KB for
TC3xx-ED). Trace2Ram requires two tiles of ED RAM (128 KB for TC2xx-ED,
512 KB for TC3xx-ED).
NOTE
Only the BR_XETK-S3.0A supports emulation memory.
