This bit performs two functions based on bit 9.
If bit 9 is cleared:

0: Stop Jog Left operation

1: Start Jog Left operation

Note that this register is a write only register and will not change state if the
web guide reaches the extreme position.
If bit 9 is set:

0: will clear the register and has no effect

1: will decrease the guide point by 0.254 mm or 1/100th of an inch
from the current value.

Note that this value on this register is momentary. Before decreasing the
guidepoint the bit needs to be cleared before setting it to one. Note that the
guide point cannot be at the extremes of the sensing window and will
automatically truncate if the extreme limit is reached. The extreme limit
depends on the sensor resolution and sensor width.
