5. FUNCTIONAL DESCRIPTIONS
5.1. ROM Area
The SPL081A provides 7.5K-byte ROM with a LCD driver that is capable of controlling 4(or 5) commons and 32 segments. (Basically, 7K bytes of ROM is available for application program and data, 0.5K bytes is allocated for test program.)
5.4. LCD Controller
SPL081A contains a LCD controller/driver that provides the capability of driving 5 commons and 32 segments LCD. LCD. To light the overhead of CPU, a display buffer is designed for mapping to A LCD dot/pattern is set ON or OFF by programming the To make the chip more corresponding bit of the display buffer.
5.2. Stop Clock Mode
The SPL081A provides a power saving mode for those applications required very low stand-by current. writing the STOP CLOCK Register ($09). previous states until being woken up. T2Hz or T16Hz wake-up. both RAM and I/Os.
