Chapter 16 Freescaleâs Scalable Controller Area Network (S12MSCANV3)
16.1.3 Features
The basic features of the MSCAN are as follows:
⢠Implementation of the CAN protocol â Version 2.0A/B
â Standard and extended data frames
â Zero to eight bytes data length
â Programmable bit rate up to 1 Mbps1
â Support for remote frames
⢠Five receive buffers with FIFO storage scheme
⢠Three transmit buffers with internal prioritization using a âlocal priorityâ concept
⢠Flexible maskable identiï¬er ï¬lter supports two full-size (32-bit) extended identiï¬er ï¬lters, or four
16-bit ï¬lters, or eight 8-bit ï¬lters
⢠Programmable wake-up functionality with integrated low-pass ï¬lter
⢠Programmable loopback mode supports self-test operation
⢠Programmable listen-only mode for monitoring of CAN bus
⢠Programmable bus-off recovery functionality
⢠Separate signalling and interrupt capabilities for all CAN receiver and transmitter error states
(warning, error passive, bus-off)
⢠Programmable MSCAN clock source either bus clock or oscillator clock
⢠Internal timer for time-stamping of received and transmitted messages
⢠Three low-power modes: sleep, power down, and MSCAN enable
⢠Global initialization of conï¬guration registers
16.1.4 Modes of Operation
For a description of the speciï¬c MSCAN modes and the module operation related to the system operating
modes refer to Section 16.4.4, âModes of Operationâ.
1. Depending on the actual bit timing and the clock jitter of the PLL.
