Field Separator 'x
Field separator preceded by a single quote, so a field
separator of the letter A would be sent as 'A (0x27 0x41).
If a Carriage Return is specified as a separator (0x27
0x0D), a final Carriage Return must still terminate the
parsing parameter string.

Ten parameters are more than enough to specify all variable length fields with a field
separator each and other status information that may be helpful to an application. More
than 10 parameters are not recommended because they use up space in non-volatile
memory (NVRAM) available for the exception table.
The parsing parameter string is stored packed in NVRAM starting at word 10, with the
total byte length stored in the high order byte of word 10. While most parameters take two
bytes of NVRAM, the following parameters take only one byte: B, D, E, S, L. None of the
parsing examples in the following section take more than 14 bytes (seven words) of
NVRAM.
The exception table starts at word 20. If the parsing parameter string extends into word 20,
then the first exception table entry is unavailable.
