12.1.1
Features
The basic features of the MSCAN are as follows:
Implementation of the CAN protocol — Version 2.0A/B
— Standard and extended data frames
— Zero to eight bytes data length
— Programmable bit rate up to 1 Mbps1
— Support for remote frames
Five receive buffers with FIFO storage scheme
Three transmit buffers with internal prioritization using a “l(fā)ocal priority” concept
Flexible maskable identier lter supports two full-size (32-bit) extended identier lters, or four
16-bit lters, or eight 8-bit lters
Programmable wakeup functionality with integrated low-pass 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 conguration registers
