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:
-- Status/Control Register (base + 04
16
)
-- Offset Register (base + 06
16
)
-- Interrupt Control Register (base + 0C
16
)
-- Calibration Flash ROM Address Register (base + 1C
16
)
-- Calibration Flash ROM Data Register (base + 1E
16
)
-- Calibration Source Register (base + 20
16
)
-- Range, Filter, Connect Channels 1 and 2 Register (base + 24
16
)
-- Range, Filter, Connect Channels 3 and 4 Register (base + 26
16

-- Trigger/Interrupt Level Channel 1 Register (base + 28
16
)
-- Trigger/Interrupt Level Channel 2 Register (base + 2A
16
)
-- Trigger/Interrupt Level Channel 3 Register (base + 2C
16
)
-- Trigger/Interrupt Level Channel 4 Register (base + 2E
16
)
-- Sample Period High Word Register (base + 30
16
)
-- Sample Period Low Word Register (base + 32
16
)
-- Pre-Trigger Count High Register (base + 34
16
)
-- Pre-Trigger Count Low Register (base + 36
16
)
-- Post-Trigger Count High Register (base + 38
16
