4. GCRAM data write
(writes data by the number of COM outputs for digits)
GCRAM (Grid Control RAM) has a 5-bit address to control the number of COM outputs for digits.
GCRAM outputs specified data directly to COMn, allowing COM outputs to be controlled arbitrarily.
It is also possible to supply a large current by connecting a plurality of COMs outside the ML9204.
For example, when COM23 and COM24 are connected, the ML9204 has 23 display digits. In this case, the user
specifies “23” as the number of display digits.
Write grid data at GCRAM addresses 00H and later.
Carry out this mode before putting-out-lights mode release.
Refer to a “setting operation flow chart” about the details of a setup.
Write COM data"0" in the GCRAM address which is not used for incorrect display prevention.
