Freescale Semiconductor
— Low power
— Good noise immunity
— Eliminates need for external current limiting resistor
— Trans conductance sized for optimum start-up margin for typical crystals
— Oscillator pins shared with GPIO functionality
1.4.5
Timer (TIM)
•
4 x 16-bit channels Timer module for input capture or output compare
•
16-bit free-running counter with 8-bit precision prescaler
1.4.6
Pulse width Modulator with Fault protection (PMF)
•
6 x 15-bit channel PWM resolution

•
Enables synchronization between PMF and ADC
•
2 trigger input sources and software trigger source
•
2 trigger outputs
•
One 16-bit delay register pre-trigger output
•
Operation in One-Shot or Continuous modes
