Byte Data Link Controller-Digital (BDLC-D)
Introduction
20.2 Introduction
The byte data link controller (BDLC) provides access to an external
serial communication multiplex bus, operating according to the Society
of Automotive Engineers (SAE) J1850 protocol.
20.3 Features
Features of the BDLC module include:
• SAE J1850 class B data communications network interface
compatible and ISO compatible for low speed (<125 kbps) serial
data communications in automotive applications
• 10.4 kbps variable pulse width (VPW) bit format
• Digital noise filter
• Collision detection
• Hardware cyclical redundancy check (CRC) generation and
checking
• Two power-saving modes with automatic wakeup on network
activity
• Polling and CPU interrupts available
• Block mode receive and transmit supported
• Supports 4X receive mode, 41.6 kbps
• Digital loopback mode
• Analog loopback mode
• In-frame response (IFR) types 0, 1, 2, and 3 supported
