Internal Clock Generator (ICG) Module
7.2.2
This section describes each pin signal in detail.
7.2.2.1
If the first write to the ICG control register 1 selected FLL engaged external or FLL bypassed modes, this
signal is the analog external/reference clock or the input of the oscillator circuit. If the first write to the ICG
control register 1 selected FLL engaged internal or self-clocked modes, this signal has no effect on the
ICG.
7.2.2.2
If the first write to the ICG control register 1 selected FLL engaged external or FLL bypassed modes using
a crystal/resonator reference, this signal is the analog output of the oscillator amplifier circuit. In all other
cases, this signal has no effect on the ICG.
7.2.3
If an external clock is used, then the pins are connected as shown below.
7.2.4
If an external crystal/resonator frequency reference is used, then the pins are connected as shown below.
