Freescale Semiconductor

— Provides a clock for rapid start-up from low power modes

— Provides a back-up clock in the event of PLL or External Oscillator clock failure

— Offers an independent clock source for the Watchdog timer

— ±5% accuracy across voltage and temperature (after factory trimming)

— Trimming registers to support frequency adjustment with in-application calibration

1.6.20

Periodic Interrupt Timer module (PIT)

The PIT features the following:

•

4 general purpose interrupt timers

•

Up to 2 dedicated interrupt timers for triggering ADC conversions

•

32-bit counter resolution

•

Clocked by system clock frequency

•

32-bit counter for Real Time Interrupt, clocked from main external oscillator

1.6.21

Real Time Counter (RTC)

Real Timer Counter supports wake-up from Low Power modes or Real Time Clock generation

•

Configurable resolution for different timeout periods

— 1 s resolution for >1 hour period

— 1 ms resolution for 2 second period

•

Selectable clock sources from external 32 KHz crystal, external 4–16 MHz crystal, internal 128 kHz RC oscillator or

divided internal 16 MHz RC oscillator

1.6.22

System Timer Module (STM)

The STM is a 32-bit timer designed to support commonly required system and application software timing functions. The STM

includes a 32-bit up counter and four 32-bit compare channels with a separate interrupt source for each channel. The counter is

driven by the system clock divided by an 8-bit prescale value (1 to 256).

•

One 32-bit up counter with 8-bit prescaler

•

Four 32-bit compare channels

•

Independent interrupt source for each channel

•

Counter can be stopped in debug mode

1.6.23

Software Watchdog Timer (SWT)

The Watchdog features the following:

•

Watchdog supporting software activation or enabled out of Reset

•

Supports normal or windowed mode

•

Watchdog timer value writable once after reset

•

Watchdog supports optional halting during low power modes

•

Configurable response on timeout: reset, interrupt, or interrupt followed by reset

•

Selectable clock source for main system clock or internal 16 MHz RC oscillator clock
