This instruction allows you to update the outputs prior to the normal output
scan. Data from the output image is transferred through a mask to the
specified outputs. The program scan then resumes.

Entering Parameters

For all micro controllers, specify O0. For 16 I/O controllers, O0/0–5 are
valid and O0/6–15 are considered unused inputs (they do not physically
exist). For 32 I/O controllers, O0/0–11 are valid and O0/12–15 are unused.

Mask – Specify a Hex constant or register address.
