The behaviour of this register is dependent upon whether its being read or written. The behaviour for the write operation
is described in Tables 24 to 27. When read the 8 MSBs of the PLL frequency counter are returned; this is described in
Tables 24 and 28.

When LockOride = 0, then automatic lock behaviour selected, PLLForceL<3:0> must be
set to ‘0000’. When LockOride = 1, then PLL manual override, PLLForceL<3:0> must
also be programmed.
These 3 bits are used to select the phase override settings; see Table 26.
