Bits 15:0 – FLSSA[15:0] Filter List Standard Start Address
Start address of standard Message ID filter list. 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”.
