Oscillator Control Registers

Write only
Bit 7-4. These bits are not used.
Bit 3. Reserved. Cleared at Reset. Must be kept
cleared.
Bit 2. Reserved. Must be kept low.
RS1-RS0. These bits select the division ratio of
the Oscillator Divider in order to generate the inter-
nal frequency. The following selctions are availa-
ble:
Note
: Care is required when handling the OSCR
register as some bits are write only. For this rea-
son, it is not allowed to change the OSCR contents
while executing interrupt service routine, as the
service routine cannot save and then restore its
previous content. If it is impossible to avoid the
writing of this register in interrupt service routine,
an image of this register must be saved in a RAM
location, and each time the program writes to
OSCR it must write also to the image register. The
image register must be written first, so if an inter-
rupt occurs between the two instructions the
OSCR is not affected.
