7.6.4 PLL Multiplier Select Register Low
Technical Data

NOTE:
NOTE:
Address:
The multiplier select bits have built-in protection such that they cannot
be written when the PLL is on (PLLON = 1).
PMSH[7:4] — Unimplemented Bits
The PLL multiplier select register low (PMSL) contains the programming
information for the low byte of the modulo feedback divider.
MUL7–MUL0 — Multiplier Select Bits
The multiplier select bits have built-in protection such that they cannot
be written when the PLL is on (PLLON = 1).

These bits have no function and always read as logic 0s.
These read/write bits control the low byte of the modulo feedback
divider that selects the VCO frequency multiplier, N. (See
and
PLLON bit in the PCTL is set. A value of $0000 in the multiplier select
registers configures the modulo feedback divider the same as a value
of $0001. Reset initializes the register to $40 for a default multiply
value of 64.
