Description
1 AGC_EN RW R 1 Automatic Gain Control (AGC) enable. When set, the
oscillation amplitude is controlled to the level selected
by CLK_ECO_CONFIG2.ATRIM. When low, the
amplitude is not explicitly controlled and can be as
high as the vddd supply. WARNING: use care when
disabling AGC because driving a crystal beyond its
rated limit can permanently damage the crystal.
27 ECO_DIV_DISABLE RW RW1C 0 ECO prescaler disable command (mutually exclusive
with ECO_DIV_ENABLE). SW sets this field to '1' and
HW sets this field to '0'.
HW sets ECO_DIV_DISABLE field to '0' immediately
and HW sets CLK_ECO_PRESCALE.ECO_DIV_EN
field to '0' immediately.
28 ECO_DIV_ENABLE RW RW1C 0 ECO prescaler enable command (mutually exclusive
with ECO_DIV_DISABLE). ECO Prescaler only works
in ACTIVE and SLEEP modes. SW sets this field to '1'
to enable the divider and HW sets this field to '0' to
indicate that divider enabling has completed. When the
divider is enabled, its integer and fractional counters
are initialized to '0'. If a divider is to be re-enabled
using different integer and fractional divider values, the
SW should follow these steps:
0: Disable the divider using the ECO_DIV_DISABLE
field.
1: Configure CLK_ECO_PRESCALE registers.
2: Enable the divider using the ECO_DIV_ENABLE
field.
HW sets the ECO_DIV_ENABLE field to '0' when the
enabling is performed and HW set
CLK_ECO_PRESCALER.ENABLED to '1' when the
enabling is performed.
