oscillator
signal input
FMIN is selected when DVS in the serial data is set to 1.
Input frequency: 10 to 160 MHz
The signal is passed through an internal divide-by-two prescaler and
then input to the swallow counter.
The divisor can be set to a value in the range 272 to 65535. Since
the internal divide-by-two prescaler is used, the actual divisor will be
twice the set value.

signal input
AMIN is selected when DVS in the serial data is set to 0.
When SNS in the serial data is set to 1:
Input frequency: 2 to 40 MHz
The signal is input to the swallow counter directly.
The divisor can be set to a value in the range 272 to 65535. The
set value becomes the actual divisor.
When SNS in the serial data is set to 0:
Input frequency: 0.5 to 10 MHz
The signal is input to a 12-bit programmable divider directly.
The divisor can be set to a value in the range 4 to 4095. The set
value becomes the actual divisor.
