Timer
Features
Introduction
Freescale Semiconductor, Inc.
• Programmable Polarity of Input Capture Edge
• Programmable Polarity of Output Compare Signal
• Alternate Counter Registers
• 16-Bit Counter
• Interrupt-Driven Operation with Three Maskable Interrupt Flags:
– Input Capture
– Output Compare
– Timer Overflow
The timer provides a timing reference for MCU operations. The input
capture and output compare functions provide a means to latch the
times at which external events occur, to measure input waveforms, and
to generate output waveforms and timing delays. Figure 42 shows the
structure of the timer module.
