This bit changes to 1 when finished entering a numerical value
with the Numerical Input. Write 0 to Numerical Input setting
clear (address+1, bit 10) to clear this bit.
1
Numerical Input setting
cancel
This bit changes to 1 when entering a numerical value with the
Numerical Input was canceled. Write 0 to Numerical Input
setting clear (address+1, bit 10) to clear this bit.
2 Backlight auto off running
The value of this bit changes to 1 when Auto Backlight OFF is
configured and the backlight was turned off by this function. To
configure Auto Backlight OFF, select the Auto Backlight OFF
check box on the System tab in the Project Settings dialog box.
