Timer Interface Module (TIM)
Technical Data MC68HC908LJ12 — Rev. 2.1
186 Timer Interface Module (TIM) Freescale Semiconductor
11.2 Introduction
This section describes the timer interface (TIM) module. The TIM is a
two-channel timer that provides a timing reference with input capture,
output compare, and pulse-width-modulation functions. Figure 11-1 is a
block diagram of the TIM.
This particular MCU has two timer interface modules which are denoted
as TIM1 and TIM2.
11.3 Features
Features of the TIM include:
• Two input capture/output compare channels:
– Rising-edge, falling-edge, or any-edge input capture trigger
– Set, clear, or toggle output compare action
• Buffered and unbuffered pulse-width-modulation (PWM) signal
generation
• Programmable TIM clock input with 7-frequency internal bus clock
prescaler selection
• Free-running or modulo up-count operation
• Toggle any channel pin on overflow
• TIM counter stop and reset bits
