Reference Voltage Attenuator (RVA)
•
Attenuation of ADC reference voltage with low long-term drift
1.3.16
Digital-to-Analog Converter Module (DAC)
•
1 digital-analog converter channel (per module) with:
— 8 bit resolution
— full and reduced output voltage range
— buffered or unbuffered analog output voltage usable
•
operational amplifier stand alone usable
1.3.17
Analog Comparator (ACMP)
•
Low offset, low long-term offset drift
•
Selectable interrupt on rising, falling, or rising and falling edges of comparator output
•
Option to output comparator signal on an external pin
•
Option to trigger timer input capture events
1.3.18
On-Chip Voltage Regulator (VREG)
•
Linear voltage regulator with bandgap reference
•
Low-voltage detect (LVD) with low-voltage interrupt (LVI)
•
Power-on reset (POR) circuit
•
Low-voltage reset (LVR)
1.3.19
Background Debug (BDM)
•
Non-intrusive memory access commands

Debugger (DBG)
•
Trace buffer with depth of 64 entries
•
Three comparators (A, B and C)
— Access address comparisons with optional data comparisons
— Program counter comparisons
— Exact address or address range comparisons
•
Two types of comparator matches
— Tagged This matches just before a specific instruction begins execution
— Force This is valid on the first instruction boundary after a match occurs
•
Four trace modes
