MEMORY ORGANIZATION

Figure 3-1 illustrates the main sections of the memory

and its address ranges:

• MCP2517FD Special Function Registers (SFR)

• CAN FD Controller Module SFR

• Message Memory (RAM)

The SFR are 32 bit wide. The LSB is located at the

lower address, e.g., the LSB of C1CON is located at

address 0x000, while its MSB is located at address

0x003.

Table 3-1 lists the MCP2517FD specific registers. The

first column contains the address of the SFR.

Table 3-2 lists the registers of the CAN FD Controller

Module. The first column contains the address of the

SFR.
