Table 95. R-Divider—Profile 1
1
Address Bits Bit Name Description
0x0650 [7:0] R R, Bits[7:0]
0x0651 [7:0] R, Bits[15:8]
0x0652 [7:0] R, Bits[23:16]
0x0653 [7:6] Unused
[5:0] R R, Bits[29:24]
1
The value stored in the R-divider register yields an actual divide ratio of one more than the programmed value.
Table 96. S-Divider—Profile 1
1
Address Bits Bit Name Description
0x0654 [7:0] S S, Bits[7:0]
0x0655 [7:0] S, Bits[15:8]
0x0656 [7:0] S, Bits[23:16]
0x0657
[7:6] Unused
[5:0] S S, Bits[29:24]
1
The value stored in the S-divider register yields an actual divide ratio of one more than the programmed value. Furthermore, the value of S must be at least 7.
