Chapter 1 Device Overview
Control bits inside the ICG determine which source is connected.
⢠FFE is a control signal generated inside the ICG. If the frequency of ICGOUT > 4 à the frequency
of ICGERCLK, this signal is a logic 1 and the ï¬xed-frequency clock will be the ICGERCLK.
Otherwise the ï¬xed-frequency clock will be BUSCLK.
⢠ICGLCLK â Development tools can select this internal self-clocked source (~ 8 MHz) to speed
up BDC communications in systems where the bus clock is slow.
⢠ICGERCLK â External reference clock can be selected as the real-time interrupt clock source.
