NOTE:
NOTE:
Address:
The PLL reference divider select register (PMDS) contains the
programming information for the modulo reference divider.
RDS[3:0] — Reference Divider Select Bits
The reference divider select bits have built-in protection such that they
cannot be written when the PLL is on (PLLON = 1).
The default divide value of 1 is recommended for all applications.

Read:
Write:
These read/write bits control the modulo reference divider that selects
the reference division factor, R. (See
Programming the
PLLON bit in the PCTL is set. A value of $00 in the reference divider
select register configures the reference divider the same as a value of
$01. (See
initializes the register to $01 for a default divide value of 1.
