Overview
1.1
Overview
The ML9620 is a microcontroller peripheral LSI which conforms to the CAN protocol for high-speed LANs in
automobiles.
The CAN Control performs communication according to the CAN protocol version 2.0 part B/Active.
The bit
rate can be programmed to values up to 1MBit/s depending on the used technology.
For the connection to the
physical layer additional transceiver hardware is required.
For communication on a CAN network, individual Message Objects (see chapter 2.3.5) are configured.
The
Message Objects and Identifier Masks for acceptance filtering of received messages are stored in the Message
RAM.
1.2
Features
The ML9620 implements the following features:
Supports CAN protocol version 2.0 part A and B
Bit rates up to 1 M Bit/s
32 Message Objects
Each Message Object has its own identifier mask
Each Message Object has its own direction mask
Each Message Object has its own extended mask
Each Message Object has its own New Data flag
Each Message Object has priority by the Message Object number
Programmable FIFO mode (concatenation of Message Objects)
Maskable interrupt
Error control:
Bit error/stuff error/CRC error/form error/acknowledgment error detection functions
Retransmission/error status monitoring function when error occurs
Bit error flag/stuff error flag/CRC error flag/form error flag/acknowledge error flag are provided
Programmable loop-back mode for self-test operation
Disabled Automatic Retransmission mode for Time Triggered CAN applications
Programmable Sleep/Stop mode function
