Address:
The PLL programming register contains the programming information
for the modulo feedback divider and the programming information for the
hardware configuration of the VCO.
MUL[7:4] — Multiplier Select Bits
Reset:
Read:
Write:
These read/write bits control the modulo feedback divider that selects
the VCO frequency multiplier, N. (See
Programming the PLL
select bits configures the modulo feedback divider the same as a
value of $1. Reset initializes these bits to $6 to give a default multiply
value of 6.
