Table 2-6. Security and integrity modulesModule DescriptionWatchdog Timer (WDOG) Watchdog Timer keeps a watch on the system functioning and resets it in case ofits failure.2.4.6 Analog modulesThe following analog modules are available on this device:Table 2-7. Analog modulesModule DescriptionAnalog-to-digital converters (ADC) 12-bit successive-approximation ADC module.Analog comparators One comparator that compares two analog input voltages across the full range ofthe supply voltage and can trigger an ADC acquisition, TPM update, or CPUinterrupt.6-bit digital-to-analog converters (DAC) 64-tap resistor ladder network which provides a selectable voltage reference forcomparator.2.4.7 Timer modulesThe following timer modules are available on this device:Table 2-8. Timer modulesModule DescriptionTimer/PWM module (TPM) • 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• Six configurable channels for input capture, output compare, or edge-alignedPWM mode• Support the generation of an interrupt and/or DMA request per channel• Support the generation of an interrupt and/or DMA request when the counteroverflows• Support selectable trigger input to optionally reset or cause the counter tostart incrementing.• Support the generation of hardware triggers when the counter overflows andper channelPeriodic interrupt timers (PIT) • One general purpose interrupt timer• Interrupt timers for triggering ADC conversions• 32-bit counter resolution• Clocked by bus clock frequency• DMA supportTable continues on the next page...Module functional categoriesKL04 Sub-Family Reference Manual, Rev. 3.1, November 201238 Freescale Semiconductor, Inc.
