Timer Interface Module B (TIMB)
20.1 Introduction
This chapter describes the timer interface module (TIMB). The TIMB is a 2-channel timer that provides a
timing reference with input capture, output compare and pulse width modulation functions. Figure 20-1 is
a block diagram of the TIMB.
The TIMB module is feature of the MC68HC908AZ60A only.
For further information regarding timers on M68HC08 family devices, please consult the HC08 Timer
Reference Manual, TIM08RM/AD.
