This message delivers the exact GPS time when an external
event is detected. The message is output within 1 µsecond
following the detection of the event.
The message is not sent out through the port specified by the
$PASHS,NME command, unless the external event is
applied to the appropriate pin on the I/O connector.
The message is therefore independent of the NMEA output
rate. It can be output at a faster or slower rate than the NMEA
rate, depending on the recurrence of the event.
The message is as follows:
$PASHR,TTT,d1,m2*cc
Where d1 and m2 .
