The frequency of this signal is equal to half of the 2OSCOUT, 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 fourth of the
XTALCLK or RCCLK frequency.
ICLK is the internal oscillator output signal (typically 50-kHz), for the
COP module and the SIM. Its frequency depends on the V
(See
The WAIT and STOP instructions put the MCU in low-power
consumption standby modes.
The WAIT instruction has no effect on the oscillator logic. OSCOUT,
2OSCOUT, and ICLK continues to drive to the SIM module.
The STOP instruction disables the XTALCLK or the RCCLK output,
hence, OSCOUT and 2OSCOUT are disabled.
The STOP instruction also turns off the ICLK input to the COP module if
the STOP_ICLKDIS bit is set in configuration register 2 (CONFIG2).
After reset, the STOP_ICLKDIS bit is clear by default and ICLK is
enabled during stop mode.
The OSCOUT, 2OSCOUT, and ICLK clocks continue to be driven out
when the device enters the break state.
