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 “local priority” concept

•

Flexible maskable identiﬁer ﬁlter supports two full-size (32-bit) extended identiﬁer ﬁlters, or four

16-bit ﬁlters, or eight 8-bit ﬁlters

•

Programmable wakeup functionality with integrated low-pass ﬁlter

•

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

1. Depending on the actual bit timing and the clock jitter of the PLL.
