SPL09A
Preliminary
FUNCTION DESCRIPTION
SPL09A provides 5K byte ROM with a LCD driver, which is capable to control 5 commons and 26 segments.
The power consumption of SPL09A is very low in both Standby mode and Halt mode. It is very appropriate for
LCD type hand-held product.
OPERATING STATES
The SPL09A provides three operating states: standby, halt, and operating. Following table shows the
differences between the three operating states.

In operating state, all modules (CPU, 32768 oscillator, timer/counter, LCD driver…) are activated. Writing the
SLEEP register ($09) enters the Halt/standby State. There are four wake-up sources in SPL09A: port IOEF
wake-up, TIMR0 wake-up, 4Hz/8Hz/16Hz/32Hz wake-up and 2Hz/1Hz wake-up. If any wake-up event occurs,
execution of the next instruction continues in the operating state.
In standby mode, all modules will be shut down, and RAM and I/Os remain in their previous states. The current
consumption is minimized. By writing to SLEEP register but keeps 32768 oscillator running, the system is in
HALT State. CPU clock is halted while it waits for an event (key press, timer overflow) to generate a wake-up in
HALT State. The 32768 related modules (timer/counter, LCD driver…) may remain active in the halt state.
Following figure is a state diagram for the SPL09A.
