Details
The binary representation of data indicates the output pattern that is written to the I/O port. For
example, a data value of 2 has a binary equivalent of 010. Line 2 is set high (1), and the other two
lines are set low (0).
Write-protected lines are not changed.
Use the tsplink.writebit() and tsplink.writeport() commands to control the output state
of the synchronization line when trigger operation is set to tsplink.TRIG_BYPASS.
The reset() function does not affect the present states of the trigger lines.
Example
tsplink.writeport(3)
Sets the synchronization lines 1 and 2 high (binary 011).

Usage
mask = tsplink.writeprotect
tsplink.writeprotect = mask
mask
An integer that specifies the value of the bit pattern for write-protect; set bits to 1 to
write-protect the corresponding TSP-Link trigger line
Details
The binary equivalent of mask indicates the mask to be set for the TSP-Link trigger line. For example,
a mask value of 5 has a binary equivalent of 101. This mask write-protects TSP-Link trigger lines 1
and 3.
Example
tsplink.writeprotect = 5
Write-protects TSP-Link trigger lines 1 and 3.
