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.
block diagram of the TIMA.
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
