1.4.3. Non-Volatile Data Storage
Non-Volatile Data Storage (NVDS) is a hybrid hardware/software scheme to implement
byte-programmable data memory and is capable of over 100,000 write cycles.
1.4.4. Internal Precision Oscillator
The internal precision oscillator (IPO) is a trimmable clock source which requires no
external components. You can select IPO frequency from one of eight frequencies
(43.2 kHz to 11.0592 MHz) and is available with factory-trimmed calibration data.
1.4.5. Crystal Oscillator
The crystal oscillator circuit provides highly accurate clock frequencies using an external
crystal, ceramic resonator, or RC network.
1.4.6. Secondary Oscillator
The secondary oscillator is a low-power oscillator, which is optimized for use with a
32 kHz watch crystal. It can be used as timer/counter clock source in any mode.
1.4.7. 10-Bit Analog-to-Digital Converter
The Analog-to-Digital Converter (ADC) converts an analog input signal to a 10-bit binary
number. The ADC supports up to eight analog input sources multiplexed with GPIO ports.
1.4.8. Low-Power Operational Amplifier
The low-power operational amplifier (LPO) is a general-purpose operational amplifier pri-
marily targeted for current sense applications. The LPO output can be internally routed to
the ADC or externally to a pin.
1.4.9. Analog Comparator
The analog comparator compares the signal at an input pin with either an internal pro-
grammable voltage reference or a second-input pin. The comparator output is used to
either drive an output pin or to generate an interrupt.
