Section 16. 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)
•
•
