Product List
The global acceptance filter provides a look-up for received identifiers for both the CAN controllers. The filter includes a CAN ID look-up table memory in which software maintains one to five sections of identifiers. As shown in the previous slide, the CAN ID look-up table memory is a 2 KB SRAM (512 words, each of 32 bits). This memory can contain up to 1024 standard frame identifiers (SFFs) or 512 extended frame identifiers (EFFs) or a mixture of both types. The CAN ID look-up table memory can be broken up into five sections, each of which lists the identifiers of certain CAN message type. The web link provided is for an application note that shows how to configure and work with the CAN interface.
