SECTION 4 DATA LINK CONTROLLER OPERATION
This section explains the operation of the MC68HC58 DLC. SAE J1850 bus interface
and general operation is the same for both the parallel and serial modes, but the meth-
od of transferring information between the host MCU and the DLC differs. Separate
discussions of serial and parallel host MCU interfaces follow the general topics. SEC-
TION 5 CONTROL AND STATUS CODES examines the specific information ex-
changed by the host MCU and the DLC.
4.1 Operating Modes
The DLC has six main modes of operation which interact with the power supplies, the
J1850 bus interface, and the host MCU interface. Refer to Figure 4-1.
