Oscillator (OSC)
7.4.5 Oscillator Out (OSCOUT)
The clock driven to the SIM is OSCXCLK. This signal is driven to the SIM
for generation of the bus clocks used by the CPU and other modules on
the MCU. OSCOUT will be divided again in the SIM and results in the
internal bus frequency being one forth of the OSCXCLK frequency or
one half of the crystal frequency.
7.5 Low-Power Modes
The WAIT and STOP instructions put the MCU in low-power-
consumption standby modes.
7.5.1 Wait Mode
The WAIT instruction has no effect on the oscillator logic. OSCXCLK
continues to drive to the SIM module.
7.5.2 Stop Mode
The STOP instruction disables the OSCXCLK output.
7.6 Oscillator During Break Mode
The oscillator continues to drive OSCXCLK when the chip enters the
break state.
