NOTE:
•
MC68HC08GP32
Address:
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
The multiplier select bits have built-in protection such that they cannot
be written when the PLL is on (PLLON = 1).
Bit7–Bit4 — Unimplemented Bits
Reset:
Read:
Write:
These read/write bits control the high byte of the modulo feedback
divider that selects the VCO frequency multiplier N. (See
Circuits
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 logic 0s.
