User Notes
1. The following limitations are imposed if no memory is used (MS = 0, MS1 = 0).
a. Dual-screen display modes are disabled.
(modes 1, 6 and 16)
b. LCD systems with Y-drivers on both sides are disabled, even if a mode for system with Y-drivers
on both sides is selected.
(modes 3, 5, 10, 12, or 14)
The HD66841 operates in exactly the same way as in the corresponding mode for a system with Y-
drivers on one side.
(modes 2, 4, 9, 11, or 13)
The CL4 pin must be left disconnected in this case.
2. With the internal register programming method, the operation of the HD66841 after a reset cannot be
guaranteed until its internal registers have been written to.
3. The memory clear function might not work normally at power-on or after a reset if the MS0 and MS1
pins or bits are not set correctly to the value corresponding to the type memory being used.
4. Since the HD66841 are a CMOS LSI, input pins must not be left disconnected. Refer to the Pin
Description and Table 1 for details on pin handling.
