1.2 CAN Related Features of the 8xC591
` CAN 2.0B active controller, supporting 11-bit Standard and 29-bit Extended indentifiers
` 1 Mbit/s CAN bus speed with 8 MHz clock achievable
` 64 byte receive FIFO (can capture sequential Data Frames from the same source as required by the Transport Layer of higher protocols such as DeviceNet, CANopen and OSEK)
` 13 byte transmit buffer
` Enhanced PeliCAN core (from the SJA1000 stand-alone CAN2.0B controller)
1.2.1 PELICAN FEATURES
` Four independently configurable Screeners (Acceptance Filters)
` Each Screener has tow 32-bit specifiers:
32-bit Match and
32-bit Mask
` 32-bits of Mask per Screener allows unique Group addressing per Screener
` Higher layer protocols especially supported in Standard CAN format with:
Up to four, 11-bit ID Screeners that also Screen the two (2) Data Bytes
i.e., Data Frames are Screened by the CAN ID and by Data Byte content
` Up to eight, 11-bit ID Screeners half of which also Screen the first Data Byte
` All Screeners are changeable "on the fly"
` Listen Only Mode, Self Test Mode
` Error Code Capture, Arbitration Lost Capture, readable Error Counters
