Analog Integrated Circuit Device Data
Freescale Semiconductor
Comments:
CS2 bit at 0 = open failure. CS2 bit at 1 = short failure.
(CS3 bit at 0 and (CS1 = 1 or CS2 =1)) = CANH failure. CS3 bit at 1 = CANL failure.
CS1 and CS0 bits: short type failure coding (gnd, VDD or VBAT).
In case of multiple failures, the last failure is reported.
