7.10.1
PLL R Divider Register
PLL R Divider: $24 - $23 – 8-bit write only
These registers set the R divider value for the PLL (Reference Divider). The PLL dividers are updated
synchronously when $24 is written. Note: $23 should be written first then $24.

7.10.2 PLL R Divider: $D4-$D3 – 8-bit read only
These registers read the respective values in registers $23 and $24 ($D3 reads back $23 and $D4 reads back
$24); see section 7.10.1 for details of bit functions.
