4.5.3 PLL Multiplier Select Register High
The PLL multiplier select register high (PMSH) contains the programming information for the high byte of
the modulo feedback divider.
MUL11–MUL8 — Multiplier Select Bits
PMSH[7:4] — Unimplemented Bits
4.5.4 PLL Multiplier Select Register Low
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
Freescale Semiconductor
These read/write bits control the high byte of the modulo feedback divider that selects the VCO
frequency multiplier N. (See
the multiplier select registers configures the modulo feedback divider the same as a value of $0001.
Reset initializes the registers to $0040 for a default multiply value of 64.
These bits have no function and always read as 0s.
These read/write bits control the low byte of the modulo feedback divider that selects the VCO
frequency multiplier, N. (See
be 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.

The multiplier select bits have built-in protection such that they cannot be
written when the PLL is on (PLLON = 1).
