ECO_DIV_ENABLED
R
RW
0
ECO prescaler enabled. HW sets this field to '1' as a
result of an CLK_ECO_CONFIG.ECO_DIV_ENABLE
command. HW sets this field to '0' as a result on a
CLK_ECO_CONFIG.ECO_DIV_DISABLE command.

ECO_FRAC_DIV
RW
R
0
8-bit fractional value, sufficient to get prescaler output
within the +/-65ppm calibration range. Do not change
this setting when ECO Prescaler is enabled.
16:25 ECO_INT_DIV
RW
R
0
10-bit integer value allows for ECO frequencies up to
33.55MHz. Subtract one from the desired divide value
when writing this field. For example, to divide by 1,
write ECO_INT_DIV=0. Do not change this setting
when ECO Prescaler is enabled.
