Table 7: Description of Extended Modem ID bits
Bit
Symbol Function/Value
D15:14 ID[1:0] {A1,A0} where A0 is the inverse polarity of the A0 pin. A1 is the inverse
polarity of XTAL_IN pin if A0 is HIGH (A0 pin is LOW), otherwise A1 is 0.
D0
LIN1 Line 1 support indicator = 1 (i.e., Line 1 is supported).
[1] Writing this register will cause a register reset: all modem registers will then take their default values.
