1.7. Programmable Current Reference (IREF0)  
Si1000/1/2/3/4/5 devices include an on-chip programmable current reference (source or sink) with two out-  
put current settings: low power mode and high current mode. The maximum current output in low power  
mode is 63 µA (1 µA steps) and the maximum current output in high current mode is 504 µA (8 µA steps).  
1.8. Comparators  
Si1000/1/2/3/4/5 devices include two on-chip programmable voltage comparators: Comparator 0 (CPT0),  
which is shown in Figure 1.13, and Comparator 1 (CPT1), which is shown in Figure 1.14. The two compar-  
ators operate identically but may differ in their ability to be used as reset or wake-up sources. See Section  
“18. Reset Sources” on page 175 and Section “14. Power Management” on page 151 for details on reset  
sources and low power mode wake-up sources, respectively.  
The comparators offer programmable response time and hysteresis, an analog input multiplexer, and two  
outputs that are optionally available at the Port pins: a synchronous “latched” output (CP0, CP1), or an  
asynchronous “raw” output (CP0A, CP1A). The asynchronous CP0A signal is available even when the  
system clock is not active. This allows the comparator to operate and generate an output when the device  
is in some low power modes.  
The comparator inputs may be connected to Port I/O pins or to other internal signals. Port pins may also be  
used to directly sense capacitive touch switches. See Application Note “AN338: Capacitive Touch Sense  
Solution” for details on Capacitive Touch Switch sensing.
