WebbAnalog Embedded processing Semiconductor company TI.com WebbA and B counters will count down by 1 every time the prescaler counts (P + 1) VCO cycles. This means the A counter will time out after ((P + 1) × A) VCO cycles. At this point the prescaler is switched to divide-by-P. It is also possible to say that at this time the B counter still has (B – A) cycles to go before it times out.
