Mode
The different dividing ratio for T
divider from divide by 3 during flash mode to divide by 4 during carrier mode. This allows the use of a 600kHz ceramic resonator during
carrier mode to obtain a better noise immunity for the receiver without a significant change in T
divider ration is obtained by a metal mask option. For final parts, this is automatically done together with the selection of flash-/carrier
mode.
