Buttons Codes
On the schematic picture of a certain controller the buttons can be assigned by the
codes given below:
When switching on the power the register 0004h will be loaded with FFFFh. This
ensures that all the buttons on the control panel will be enabled.
If we want to disable any of the buttons, the code of that button must be subtracted from
FFFFh and the resulting value must be written back to register 0004h. After this
procedure the disabled buttons will not work. If we write 0000h into register 0004h: all of
the buttons will be disabled.
After switching the power Off/On the buttons (all of them) will be enabled again.
If we write a button code into register 0006h: this will simulate a press on that button
(even if the button is presently disabled).
Special combination of buttons:
Values can be written into 0008h register, the result:
– 0001h: Simulates that
