Timer Interface Module A (TIMA)
11.2 Introduction
This section describes the timer interface module A (TIMA). The TIMA is
a four-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 TIMA.
11.3 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 eight channels
