TCCR1A and TCCR1B are different registers, but they work on the same timer, timer1. They configure different behavior and are located in separate registers, simply because all the bits don’t fit in a single byte.
What is ICR1?
ICR1. The Input Capture register can be used to measure the time between pulses on the external ICP pin (Input Capture Pin). How this pin is connected to ICR is set with the ICNC and ICES bits in TCCR1A.
What is TCCR0A?
As to what the “A” and “B” mean (TCCR0A and TCCR0B), there are two registers that are used to control the timer. They each serve a different purpose. TCCR0A has bits that control PWM, and TCCR0B has bits that control the timer itself.
