• Inverting and non-inverting 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
• Comparator and reference generator can be powered down
• Input Multiplexer
The Comparator_A+ block diagram is shown in Figure 21-1.
