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.
