Module
Description
Watchdog timer keeps a watch on the system functioning and resets it in case of
its failure.
2.4.6 Analog modules
The following analog modules are available on this device:
Table 2-7. Analog modules
Module
Description
Analog-to-digital converters (ADC)
12-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
interrupt.
6-bit digital-to-analog converters (DAC)
64-tap resistor ladder network which provides a selectable voltage reference for
comparator.
2.4.7 Timer modules
The following timer modules are available on this device:
Table 2-8. Timer modules
Module
Description
• 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-
down
• Two configurable channels for input capture, output compare, or edge-
aligned PWM mode
• Support the generation of an interrupt per channel
• Support the generation of an interrupt when the counter overflows
• Support selectable trigger input to optionally reset or cause the counter to
start incrementing.
• Support the generation of hardware triggers when the counter overflows and
per channel
• 16-bit time counter or pulse counter with compare
• Configurable clock source for prescaler/glitch filter
• Configurable input source for pulse counter
