8.2

Configuration of 8/16-bit Capture Timer/Counter

The 8/16-bit capture timer/counter consists of the following seven blocks:
• Count clock selectors 0/1
• Counter circuits 0/1
• Square wave output control circuit
• Timer 0/1 data registers (TDR0, TDR1)
• Timer 0/1 control registers (TCR0, TCR1)
• Capture data registers (TCPL, TCPH)
• Timer output control register (TCR2)
