Timer Interface A (TIMA)
16.1 Introduction
This section describes the timer interface module A (TIMA). The TIMA is a 4-channel timer that provides:
• Timing reference with input capture
• Output compare
• Pulse-width modulator functions
Figure 16-2 is a block diagram of the TIMA.
16.2 Features
Features of the TIMA include:
• 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 modulator (PWM) signal generation
• Programmable TIMA clock input:
– 7-frequency internal bus clock prescaler selection
– External TIMA clock input (4-MHz maximum frequency)
• Free-running or modulo up-count operation
• Toggle any channel pin on overflow
• TIMA counter stop and reset bits
