Clock Concept
The on-chip clock generator provides the INCA-D with all necessary clock signals.
Generally, the INCA-D derives its system clocks from an external crystal of 15.36 MHz
connected to XTAL1 and XTAL2. An external clock signal may be fed to the input XTAL1,
leaving XTAL2 open.
The clock signals for the different device modules are generated as described in Figure
4-1. When not disabled by setting bit PPLEN in register CLK_CONF, the on chip PLL
generates a signal with a frequency of 96 MHz which is the input signal to a set of fixed
and programmable divider. The outputs of the divider are the clock signals for the
different device components, which can be disabled separately.
