0 A low input on Paper Sensor #1 is True
1 A high input on Paper Sensor #1 is True
0 The Misc I/O #1 pin is configured as an input.
1 The Misc I/O #1 pin is configured as an output.
Level sensitive: Paper Sensor #1 State bit (in Status
Register) is set to a 1 if Paper Sensor #1 is currently
True.
Edge sensitive: Paper Sensor #1 State bit (in Status
Register) is set to a 1 if Paper Sensor #1 has been
True since the last time the Status Register was read.
Transitions on Paper Sensor #1 will not clear the
scanning bit.
A False - to - True transition on Paper Sensor #1 will
clear the Command Register and stop the scan.
A low input on Paper Sensor #2 is True
A high input on Paper Sensor #2 is True
Level sensitive: Paper Sensor #2 State bit (in Status
Register) is set to a 1 if Paper Sensor #2 is currently
True.
Edge sensitive: Paper Sensor #2 State bit (in Status
Register) is set to a 1 if Paper Sensor #2 has been
True since the last time the Status Register was read.
Transitions on Paper Sensor #2 will not clear the
scanning bit.
A False - to - True transition on Paper Sensor #2 will
clear the Command Register and stop the scan (after
the number of lines specified in the Fullsteps to Scan
after Paper Sensor #2 trips register).
A low input on Misc I/O #1 is True
A high input on Misc I/O #1 is True
Level sensitive: Misc I/O #1 State bit (in Status
Register) is set to a 1 if Misc I/O #1 is currently True.
Edge sensitive: Misc I/O #1 State bit (in Status
Register) is set to a 1 if Misc I/O #1 has been True
since the last time the Status Register was read.
The output of the Misc I/O #1 pin will be a logic low
(0V).
The output of the Misc I/O #1 pin will be a logic high
(5V).
The Misc I/O #2 pin is configured as an input.
The Misc I/O #2 pin is configured as an output.
A low input on Misc I/O #2 is True
A high input on Misc I/O #2 is True
Level sensitive: Misc I/O #2 State bit (in Status
Register) is set to a 1 if Misc I/O #2 is currently True.
Edge sensitive: Misc I/O #2 State bit (in Status
Register) is set to a 1 if Misc I/O #2 has been True
since the last time the Status Register was read.
The output of the Misc I/O #2 pin will be a logic low
(0V).
The output of the Misc I/O #2 pin will be a logic high
(5V).
n lines (register 44) saved in SRAM for every m lines
scanned. m = 1 to 255.
If m = 0 then function is bypassed
