Fig. 21–2:
For the effect of CPU clock modes on the operation of this
module refer to section “CPU and Clock System” (see
Table 4–1 on page 37). During Power Saving mode the LCD
Logic is switchted off, the port outputs are held at low level
but the port register contents will be preserved.
21.1.5. Cascading of LCD Driver Modules
For expansion purposes, the LCD module may be cascaded
with external LCD driver ICs. Master or slave mode is select-
able for the LCD module while in standby. Special signals

provide phase and frequency synchronism for the LCD frame
among the cascaded ICs.
For master mode, set flag LCDSLV in register ULCDLD
LOW. The module always directs signal LCD-SYNC-OUT to
pins U8.5 and LCD-CLK-OUT to pins U8.3. They connect to
external slave ICs’ SYNC-IN and CLK-IN inputs for synchro-
nization.
For slave mode, set flag LCDSLV in register ULCDLD HIGH.
Configure pins U8.4 and U8.2 to receive signals LCD-SYNC-
IN and LCD-CLK-IN from an external master IC’s SYNC-
