MICR Commands and Parsing
3255 4073–002 11–5
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.
