4 POSITIONING DEDICATED SIGNALS
(3) Error detection signal (M2407+20n) .......................... Status signal
(a) This signal turns on with detection of a minor error or major error, and it is
used as judgement of the error available/not available.
The applicable error code
register with detection of a minor error. (Refer to Section 4.2.1 (4))
The applicable error code
register with detection of a major error. (Refer to Section 4.2.1 (5))
(b) This signal turns off when the error reset command (M3207+20n) turns on.
