Table 2-8. Timer modules (continued)
Module Description
Flexible timer modules (FTM) • Selectable FTM source clock, programmable prescaler
• 16-bit counter supporting free-running or initial/final value, and counting is up
or up-down
• Input capture, output compare, and edge-aligned and center-aligned PWM
modes
• Operation of FTM channels as pairs with equal outputs, pairs with
complimentary outputs, or independent channels with independent outputs
• Deadtime insertion is available for each complementary pair
• Generation of hardware triggers
• Software control of PWM outputs
• Up to 4 fault inputs for global fault control
• Configurable channel polarity
• Programmable interrupt on input capture, reference compare, overflowed
counter, or detected fault condition
• Quadrature decoder with input filters, relative position counting, and interrupt
on position count or capture of position count on external event
• DMA support for FTM events
Periodic interrupt timers (PIT) • Four general purpose interrupt timers
• Interrupt timers for triggering ADC conversions
• 32-bit counter resolution
• Clocked by system clock frequency
• DMA support
Low-power timer (LPTimer) • Selectable clock for prescaler/glitch filter of 1 kHz (internal LPO), 32.768 kHz
(external crystal), or internal reference clock
• Configurable Glitch Filter or Prescaler with 16-bit counter
• 16-bit time or pulse counter with compare
• Interrupt generated on Timer Compare
• Hardware trigger generated on Timer Compare
Carrier modulator timer (CMT) • Four CMT modes of operation:
• Time with independent control of high and low times
• Baseband
• Frequency shift key (FSK)
• Direct software control of CMT_IRO pin
• Extended space operation in time, baseband, and FSK modes
• Selectable input clock divider
• Interrupt on end of cycle with the ability to disable CMT_IRO pin and use as
timer interrupt
• DMA support
Real-time clock (RTC) • Independent power supply, POR, and 32 kHz Crystal Oscillator
• 32-bit seconds counter with 32-bit Alarm
• 16-bit Prescaler with compensation that can correct errors between 0.12
ppm and 3906 ppm
