Comparator E (COMP_E) Module
35.1 COMP_E Introduction
The COMP_E module supports precision slope analog-to-digital conversions, supply voltage supervision,
and monitoring of external analog signals.
Features of COMP_E include:
•
Inverting and noninverting terminal input multiplexer
•
Software-selectable RC filter for the comparator output
•
Output provided to Timer_A capture input
•
Software control of the port input buffer
•
Interrupt capability
•
Selectable reference voltage generator and voltage hysteresis generator
•
Reference voltage input from shared reference
•
Ultra-low-power comparator mode
•
Interrupt driven measurement system for low-power operation support
shows the Comparator_E block diagram.
