Bits 15:0 – RBSA[15:0] Rx Buffer Start Address
Configures the start address of the Rx Buffers section in the Message RAM. Also used to reference
debug message A,B,C. When the CAN module addresses the Message RAM it addresses 32-bit words,
not single bytes. The configurable start addresses are 32-bit word addresses, i.e. only bits 15 to 2 are
evaluated, the two least significant bits are ignored. Bits 1 to 0 will always be read back as “00”.
