The
[AI
key, for example, corresponds to buffer address 2 and bit 1.
When the [AJ key is pressed, buffer address 2 becomes "0002H".
If several keys are pressed simultaneously, all the corresponding bits are
turned ON.
The operation key numbers
(XO
to
X3F)
have no connection with the instal-
lation position of the G-controller module to the base unit.
