1. At this point, bits R13, R14 and R15 are stored and sent to the ‘‘OSC or 4–Stage Divider” block in the Block Diagram. Bits R0 through
R12 are loaded into the first buffer in the double–buffered section of the R register. Therfore, the R counter divide is not altered yet and
retains the previous ratio loaded. The C and A registers are not affected.
2. Optional load pulse. At this point, the bits R0 through R12 are transfered to the second buffer of the R register. The R counter begins dividing
by the new ratio after completing the rest of the present count cycle. CLK must be low during the ENB pulse, as shown. The C and A registers
are not affected. The first buffer of the R register is not affected. Also, see note of Figure 24 for an alternate method of loading the second
buffer in the R register.
