(always read this register twice to make sure its value
was not changing while it was being read)
0 False

Paper Sensor #1 State
If this input is edge sensitive, reading this
Status Register will clear it.
Paper Sensor #2 State
If this input is edge sensitive, reading this
Status Register will clear it.
Misc I/O #1 State
If this input is edge sensitive, reading this
Status Register will clear it.
Misc I/O #2 State
If this input is edge sensitive, reading this
Status Register will clear it.
Pause
This bit indicates whether or not the scanner
is currently paused due to a buffer full
condition.
Powerdrop
This bit is used to detect if the power supply
has dipped below 3V since the last time this
register was read. Reading this register
clears this bit.

False: Power has not dipped below 3V since the last
time this register was read

True: Power hasdipped below 3V since the last time
the register was read
DATAPORT REGISTERS

N/A
Address of location to be read/written to.
a = 0 to 1023 for gamma tables,
0 to 2729 for Offset/Gain Coefficient Data (300dpi),
0 to 5459 for Offset/Gain Coefficient Data (600dpi).
Addresses greater than these are illegal.
Bit D5 of register 4 indicates whether next operation
will be a Read (D5=1) or a Write (D5=0)
Data to be read from or written to the address of the
currently selected Dataport Target. The DataPort
Address is automatically incremented whenever one
(Gamma) or two (Offset/Gain Coefficient Data) bytes
are read from or written to this register.
DataPort Target Color
(Note: If using 1
Channel Mode A, the color for the gamma
table is selected by register 26, bits 3 and 4,
not this register)
