Table 2-6. Security and integrity modules

Watchdog timer keeps a watch on the system functioning and resets it in case of

its failure.

Table 2-7. Analog modules

16-bit successive-approximation ADC module.

One comparator that compares two analog input voltages across the full range of

the supply voltage and can trigger an ADC acquisition, TPM update, or CPU

64-tap resistor ladder network which provides a selectable voltage reference for

Supplies an accurate voltage output that is trimmable in 0.5 mV steps. The VREF

can be used in medical applications, such as glucose meters, to provide a

reference voltage to biosensors or as a reference to analog peripherals, such as

the ADC, DAC, or CMP.

Low-power general-purpose DAC, whose output can be placed on an external pin

or set as one of the inputs to the analog comparator or ADC.

• Selectable TPM clock mode

• Prescaler divide-by 1, 2, 4, 8, 16, 32, 64, or 128

• 16-bit free-running counter or modulo counter with counting be up or up-

• configurable channels for input capture, output compare, edge-aligned PWM

mode, or center-aligned PWM mode
