FUNCTIONAL DESCTRIPTION
Figure 1. Rx. Register Programming Timing
Programmable N-counter consists of 2-bits Swallow Counter, 4/5 Dual modulars Prescaler and 14-bits Main
Counter
The Divide Ratio is;
N = (P + 1)
×
S + P (M
S) = PM + S;
— P = Dual Modulars Prescaler (4)
— S = 2-bits Swallow Counter value (0 ~ 3)
— M = 14-bits (7 ~ 16383)
— N = Programmable N-Counter value (N > S; 28 ~ 65535)
