5.4.6.3 Bit Timing Error
5.4.6.4 BREAK Error
5-14
MOTOROLA
This value indicates that a bit in the received frame did not match the timing window
stored in the control logic. The receiver immediately places a completion code byte in
the buffer upon detection of this error. This generally occurs as a result of mismatched
clock divisors between nodes, but may occur if a BREAK is detected after the J1850
bus has been passive for 8 to 34 s. When this occurs, two completion codes (a bit
error and a break) are generated.
This value indicates that a BREAK symbol was detected on the J1850 bus, or the
J1850 bus was shorted high for longer than the defined BREAK period, and has re-
covered.
