7.6.4 PLL Multiplier Select Register Low
Technical Data
128
NOTE:
Address:
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).

Write:
These read/write bits control the low byte of the modulo feedback
divider that selects the VCO frequency multiplier, N. (See
Circuits
written when the 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.
