Where:
LIN ERROR = Or function of all LIN Errors
Error LED1 = function ERRLED1[2:0] ≠ 0; refer to Table 8
Error LED2 = function ERRLED2[2:0] ≠ 0; refer to Table 8
Error LED3 = function ERRLED3[2:0] ≠ 0; refer to Table 8
RETRY STATE = NCV7430 is retrying to recover from errors
VBB Under Voltage = “0” at power on reset. Set to a “1” with VBB under voltage. Cleared with a GET_FULL_STATUS
command.
