124 Register-Based Programming Appendix B
Register Descriptions
There are twenty WRITE and thirty-one READ registers on the digitizer.
This section contains a description of the registers followed by a bit map of
the registers in sequential address order. Undefined register bits appear as
"0" when the register is read, and have no effect when written to.
WRITE Registers You can write to the following digitizer registers:
