COMPARATORS
A separate synchronous serial interface sup-
ports two industry-standard protocols (SPI
and Microwire
) for interfacing to standard
devices such as an ADC, allowing for peripheral
expansion such as the use of a digitizer pen.
Power Management
The CL-PS7110 is designed for low-power
operation. There are three basic power states:
G
Standby —
puter being switched off (no display), and the
main oscillator is shut down. Only the realtime
clock is running.
This state is equivalent to the com-
G
Idle —
all oscillators are running, but the processor
clock is halted while waiting for an event such as
a key press.
In this state,
the device is functioning and
G
Operating —
state, except that the processor clock is running.
This state is the same as the idle
