Oscillator (OSC)
7.8.1 Wait Mode
7.8.2 Stop Mode
7.9 Oscillator During Break Mode
Data Sheet
110
The WAIT instruction has no effect on the oscillator module. CGMXCLK
continues to drive to the clock generator module, and OSCCLK
continues to drive the timebase module.
The STOP instruction disables the x-tal or the RC oscillator circuit, and
hence the CGMXCLK clock stops running. For continuous x-tal or RC
oscillator operation in stop mode, set the STOP_XCLKEN (for x-tal) or
STOP_RCLKEN (for RC) bit to logic 1 before entering stop mode.
The internal oscillator clock continues operation in stop mode. It can be
disabled by setting the STOP_ICLKEN bit to logic 1 before entering stop
mode.
The oscillator continues to drive CGMXCLK when the device enters the
break state.
