Philips's LPC2000 series 32-bit ARM microcontroller embedded acceptance filter for the CAN controller provides a global identifier query function, to achieve complex message ID filtering, and can greatly reduce the burden on the microcontroller. In normal mode, when the receiving end of the CAN controller receives a complete identifier, it will notify the receiving acceptance filters. Acceptance filter for the CAN controller provides global packet identification filtering. It contains a 512 × 32 (2 KB) of RAM, in which 2 KB of RAM can be set from 1 to 5 message identifier table, laptop battery to form a lookup table LUT (LookUp Table). Entire lookup table can accommodate 024 or 512 standard identifier extension identifier, or a mixture of two types of identifiers. 5 possible identifiers table includes FullCAN standard identifier table and a separate standard identifier tables, standard identifier range table, separate tables, and extended identifier extension identifier range table. 1.2 Acceptance filter function, LPC2000 family of ARM microcontrollers CAN acceptance filter has two operating modes: one is the general pattern of laptop batteries; another called "FullCAN mode." Acceptance filter response to this signal, the read CAN controller number and identifier size (standard or extended identifier Identifier 11 29); then search LUT, look for a matching identifier. If a matching identifier, the notification will be received by the CAN controller into the CAN controller receives the packet buffer; Otherwise, discard the received information to the frame.
