Figure 26-107. Example of FlexRay Memory Layout (MCR[FAM] = 0)
26.6.4.2 FlexRay Memory Layout (MCR[FAM] = 1)
Figure 26-108 shows an example layout for the FIFO address mode MCR[FAM] = 1. The following set of
rules applies to the layout of the FlexRay memory:
• The FlexRay memory consists of two contiguous regions.
• The size of each region is maximum 64 Kbytes.
• Each region start at a 16 byte boundary.
