Timer Interface Module A (TIMA)
Introduction
This section describes the timer interface module (TIMA). The TIMA is a
four-channel timer that provides a timing reference with input capture,
output compare, and pulse-width-modulation functions. Figure 1 is a
block diagram of the TIMA.
Features
Features of the TIMA include the following:
• Four 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 TIMA clock input
– Seven-frequency internal bus clock prescaler selection
– External TIMA clock input (4MHz maximum frequency)
• Free-running or modulo up-count operation
• Toggle any channel pin on overflow
• TIMA counter stop and reset bits
• Modular architecture expandable to 8 channels
