These values are internally summed with 16, and thus,
the min and max divider becomes approximately 19
and 28. These limits MUST be followed, to prevent the
delta-sigma number generator from overflowing.
Whenever all of the fhi[11:0] and flo[11:0] are zero, only
an integer divider is used, and the delta-sigma modula-
tor is not in operation. This allows lower current opera-
tion. The 600kHz PLL bandwidth could be used in this
mode to reduce phase noise.

NAME
FUNCTION
0
fload
Effectively changes the PLL frequency to the ones written in registers 25. This is a self-reset bit,
and is reset to zero after the operation is completed.

BIT
NAME
FUNCTION
0
datain_bit
SPI equivalent of DIN, where the transmitted data can be controlled through the SPI interface. It
should be kept low (0) if only the external DIN pin is used. The external DIN pin should also be kept
low (0) if the SPI datain_bit is used.

NAME
FUNCTION
0
enable_bit
SPI equivalent of ENABLE. It should be kept low (0) if the external ENABLE pin is used. The external
ENABLE pin should also be kept low (0) if the SPI enable_bit is used.
