Frequency Locked Loop Coarse Counter (Reg 5)
This register contains the ”coarse” FLL counter
value for the FLL. This register gives a worst case
resolution of 16µs with the worst case (i.e. slow-
est) 4MHz clock and has a valid range of 001 to
FFF hex.
Reg: 5
Name: FLL Coarse Counter Register
Type: Write Only

Frequency Locked Loop Fine Counter (Reg 6)
This register contains the ”fine” counter value of
the FLL. The worst case resolution (i.e. with a
4MHz clock) is 1µs. It is important that the
most significant bit of this register must be a
zero when a write is made. Valid writes to this
register must be between 001 and 7FF hex.
Reg: 6
Name: FLL Fine Counter Register
Type: Write only.
