63: Reference Data
Table 6-23.
REFERENCE DATA: addresses 52 – 63 allow reference data to be read for each key, starting
with key 0. There are two bytes of data for each key. These are the key’s 16-bit reference data
which is accessed as two 8-bit bytes, stored LSB first. These addresses are read-only.
Table 6-24
the left-most column have the highest priority, those in the second-left have the next priority etc.
If two or more settings are incompatible then the setting in the left-hand column overrides the
other. The right-most column, I/O Function, specifies the expected result.
