When payload sizes of 16, 32, or 64 bytes are configured in some or all RAM blocks, thetotal number of MBs and its respective number order may differ from the defaultconfiguration of 8 bytes. For example, suppose Block0 is configured to 8 bytes payload,Block1 to 16 bytes, Then the following table indicates how the message buffers will bearranged in RAM.Table 49-14.
