OSC1 pin is an input to the crystal oscillator amplifier. Schmitt trigger and
glitch filter are implemented on this pin to improve EMC performance.
See
glitch filter.
OSC2 pin is the output of the crystal oscillator inverting amplifier.
The SIMOSCEN signal from the system integration module (SIM)
enables/disables the internal RC and x-tal oscillator circuits.
The ICLK clock is the output from the internal RC oscillator. This clock
drives the SIM and COP modules.
The CGMXCLK clock is the output from the x-tal oscillator. This clock
drives to CGM, real time clock module, analog-to-digital converter, liquid
crystal display driver module, 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 WAIT and STOP instructions put the MCU in low-power
consumption standby modes.
