The MCAN module is configured to allocate 4352 words in the Message RAM. The Message RAM has a width of 32 bits.
The Message RAM is capable to include each of the sections listed in Figure 12-292. It is not necessary to configure each of the sections (a section in the Message RAM may be 0) and there is not restriction with respect to the sequence of the sections. For parity checking or ECC a respective number of bits has to be added to each word.
When the MCAN module addresses the Message RAM it addresses 32-bit words. The start addresses are configurable and they are 32-bit word addresses.
The element size can be configured for:
The Host CPU configures the following information in the Message RAM:
The MCAN module does not check for errors in the Message RAM configuration. The configuration of the start addresses of the different sections and the number of elements of each section has to be done carefully. This will prevent falsification or loss of data.
