Description:
ECO Prescaler Configuration Register
Address:
0x40261520
Offset:
0x1520
Retention:
Retained

Description
0 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.
8:15 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.
