Timer Interface Module A (TIMA)
25.1 Introduction
This section describes the timer interface module (TIMA). The TIMA is a 6-channel timer that provides a
timing reference with input capture, output compare and pulse-width-modulation functions. Figure 25-1 is
a block diagram of the TIMA.
For further information regarding timers on M68HC08 family devices, please consult the HC08 Timer
Reference Manual, TIM08RM/AD.
25.2 Features
Features of the TIMA include:
⢠Six Input Capture/Output Compare Channels
â Rising-Edge, Falling-Edge or Any-Edge Input Capture Trigger
â Set, Clear or Toggle Output Compare Action
⢠Buffered and Unbuffered Pulse Width Modulation (PWM) Signal Generation
⢠Programmable TIMA Clock Input
â 7 Frequency Internal Bus Clock Prescaler Selection
â 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
