Note 1: Set time is an internal 10 millisecond (T10) count since power-on initialisation enabled the processor interrupts. It is not used
to derive GPS time, but only serves to provide a sequence of events knowledge. The set time or T10 count references the receiver’s
internal time at which the message was created for output. The T10 range is approximately 71 weeks.
Note 2: The sequence number is a count that indicates whether the data in a particular binary message has been updated or
changed since the last message output.
Note 3: The options list is a bit-encoded configuration word represented as an ASCII four-digit hexadecimal number:
bit 0 minimises ROM usage
bit 1 minimises RAM usage
bits 2-15 reserved
