Freescale Semiconductor
When the x-tal oscillator is selected, OSC2 pin is the output of the crystal
oscillator inverting amplifier.
When the RC oscillator or internal oscillator is selected, OSC2 pin is the
output of the internal bus clock.
The SIMOSCEN signal from the system integration module (SIM)
enables/disables the x-tal oscillator, the RC-oscillator, or the internal
oscillator circuit.
The CGMXCLK clock is output from the x-tal oscillator, RC oscillator or
the internal oscillator. This clock drives to CGM and other MCU sub-
systems.
This is buffered signal of CGMXCLK, it is used by the CGM as the
phase-locked-loop (PLL) reference clock.
The OSCCLK is the reference clock that drives the timebase module.
See
The WAIT and STOP instructions put the MCU in low-power
consumption standby modes.
