Timer Interface B (TIMB)
12.2 Introduction
This section describes the timer interface module (TIMB). The TIMB is a
2-channel timer that provides:
• A timing reference with input capture
• Output compare
• Pulse width modulation (PWM) functions
Refer to Figure 12-1 for a block diagram of the TIMB and to Figure 12-2
for a summary of the registers.
For further information regarding timers on M68HC08 family devices,
please consult the HC08 Timer Reference Manual, TIM08RM/AD.
12.3 Features
Features of the TIMB include:
• Two 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 PWM signal generation
• Programmable TIMB clock with 7-frequency internal bus clock
prescaler selection
• Free-running or modulo up-count operation
• Toggle any channel pin on overflow
• TIMB counter stop and reset bits
