Latch
Note: Setting bit 3 to '1' allows the user to overide the Latch value from pin 5 via use of bits 2 and 1. Use the values from the PLL Operating
Mode Readback Table. Note that Bits 7 and 6 will keep the value originally latched on pin 5. A warm reset of the system will have to
accomplished if the user changes these bits.
