This anomaly applies to IC Rev. Engineering A, build codes QFAA-AA0, QFAA-AC0, CGAA-AA0.
Only the first 32 kB of Data RAM or Code RAM are functional. The contents of Data and Code RAM are independent; values written to one cannot be read from the other.
Always.
All RAM can be used for data variables without limitation. If Code is run from the SRAM segment of the System Address Map (Data RAM), execution will take longer because wait states will be introduced. EasyDMA transfers to and from RAM must be performed in the SRAM segment of the System Address Map (Data RAM).
