8-2
The J1850 controller can handle network protocol functions including message frame sequenc-
ing, bit arbitration, in-frame response (IFR) messaging, error detection, and delay compensation.
The J1850 communications controller (Figure 8-2) consists of a control state machine (CSM),
symbol synchronization and timing (SST) circuitry, six control and status registers, transmit and
receive buffers, and an interrupt handler.
