digio.writeprotect

digio.writeprotect
This attribute contains the write-protect mask that protects bits from changes from the digio.writebit() and
digio.writeport() functions.
Type TSP-Link accessible
Attribute (RW) Yes
Usage
mask = digio.writeprotect
digio.writeprotect = mask
mask
Details
Bits that are set to one cause the corresponding line to be write-protected.
The binary equivalent of mask indicates the mask to be set for the I/O port. For example, a mask value of 7 has a
binary equivalent of 00000000000111. This mask write-protects Lines 1, 2, and 3.
Example
digio.writeprotect = 15
