Timer Interface Module B (TIMB)
Introduction
This section describes the timer interface module (TIMB). The TIMB is a
two-channel timer that provides a timing reference with input capture,
output compare, and pulse-width-modulation functions. Figure 9 is a
block diagram of the TIMB.
Features
Features of the TIMB include the following:
• 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 TIMB clock input
– Seven-frequency internal bus clock prescaler selection
– External TIMB Clock Input (4-MHz Maximum Frequency)
• Free-running or modulo up-count operation
• Toggle any channel pin on overflow
• TIMB counter stop and reset bits
• Modular architecture expandable to 8 channels
