Figure 2. Ref. Register Programming Timing
NOTE:
It is possible to use Optional selection of EN1, EN2 (when used EN)
The Input Reference Frequency (X-tal Oscillator) will divided by 1/4 Prescaler, and then divided by Pre-
programmed R-counter value once more.
Programmable R-Counter consists of Fixed 1/4 Prescaler, 14-bits Programmable Counter
When FRC = 0, Fixed 1/4 Prescaler is used and 14-bits counter & can divide Multiple 4
RD = 4, R = 28 (=4 x 7) ~ 65532 -- (Min. Divide value:7)
When FRC = 1, Fixed 1/4 Prescaler isn
’t
used, but using 14-bits counter & Can divide all value
RD = R = 7 ~ 16384 [All value] --- (Min. Divide value:7)
Ex 1) FRC = 0, In case of 14-bits Program, Fosc = 12.8MHz and fixed 1/4 prescaler is used
[(Osc. Freq. / Prescaler) / Ref. Freq.] = [(12.8MHz / 4) / 6.25kHz] = 512
