EXAMPLE 4-2:
4.2.6.4
If the device enters Sleep mode during a clock switch
operation, the clock switch operation is aborted. The
processor keeps the old clock selection and the
OSWEN bit (OSCCON<0>) is cleared. The WAIT
instruction is then executed normally.
4.2.6.5
The SOSC can be used by modules, as well as the
CPU. Therefore, the SOSC is controlled by a combina-
tion of software and hardware. Setting the SOSCEN bit
(OSCCON<1>) to a ‘1’ enables the SOSC. The SOSC
is disabled when it is not being used by the CPU mod-
ule and the SOSCEN bit is ‘0’. If the SOSC is being

used as SYSCLK, such as after a clock switch, it can-
not be disabled by writing to the SOSCEN bit. If the
SOSC is enabled by the SOSCEN bit, it will continue to
operate when the device is in SLEEP. To prevent inad-
vertent clock changes the OSCCON register is locked.
It must be unlocked prior to software enabling or
disabling the SOSC.

The pins used by the POSC and SOSC are shared by
other peripherals modules. Table shows the function of
these shared pins in the available oscillator modes.
When the pins are not used by a oscillator they are
available for use as general I/O pins or by use by a
peripheral sharing the pin.
