1) This column shows whether a suspend acknowledge from a FDR controlled module depends on the module’s
state or not. If a suspend acknowledge depends from the module state, typically module operations such as
serial transmissions are terminated before a suspend request is acknowledged back to the fractional divider.
Note that bit FDR.SM must be cleared (granted suspend mode selected) when using the suspend mode
acknowledge/grant functionality. If immediate suspend mode is selected (FDR.SM = 1), Suspend Mode is
entered at once (if FDR.SC not equal 00
B
) independently from the suspend acknowledge answer from the
module.
2) This column shows whether the External Clock Enable input of a fractional divider is controlled by on-chip
hardware (source module see comment) or not (“–”).
