FFE is a control signal generated inside the ICG. If the frequency of ICGOUT is great than 4 × the
frequency of ICGERCLK, this signal is a logic 1 and the fixed-frequency clock is ICGERCLK/2.
Otherwise the fixed-frequency clock is BUSCLK.
ICGLCLK — Development tools can select the internal self-clocked source (~ 8 MHz) to speed
up BDC communications in systems where the bus clock is slow.
ICGERCLK — External reference clock can be selected as the real-time interrupt clock source.
Can also be used as the ALTCLK input to the ADC module.
