Address 100 – 163: Signals and References
Addresses 100 – 131 allow signal data to be read for each key. There are two bytes of data for each key. These are
the key 16-bit signal which is accessed as two 8-bit bytes, stored LSB first.
Addresses 132 – 163 allow reference data to be read for each key. There are two bytes of data for each key. These
are the key 16-bit reference which is accessed as two 8-bit bytes, stored LSB first.
There are a total of 16 keys and 4 bytes of data per key, yielding a total of 64 addresses. These addresses are read-
