36.2.23 Receive Rule Entry Register jCH (GAFLPHj) (j = 0 to 15)
x: Don’t care
Modify the GAFLPHj register only when the GRWCR.RPAGE bit is set to 0 in global reset mode.
GAFLPTR[11:0] Bits (Receive Rule Label)
These bits are used to set a 12-bit label to be attached to messages that have passed through the filter. A label is attached
when a message is stored in the receive buffer or the FIFO buffer.
GAFLDLC[3:0] Bits (Receive Rule DLC)
These bits are used to set the minimum data length necessary for receiving messages. If the data length of a message that
is being filtered is equal to or larger than the value set by the GAFLDLC[3:0] bits, the message passes the DLC check.
Setting these bits to 0000b disables the DLC check function allowing messages with any data length to pass the DLC
check.
