RETURN
The device data sheet states when an INTOSC
frequency is selected (125, 250, 500 kHz, 1, 2, 4,
8 MHz), the frequency will be stable when the
IOFS bit becomes set (IOFS = 1) at 4 ms. The
following applies for applications relying on time
dependent code.
Under the following conditions, any of the INTOSC
frequencies may not be stable when IOFS
becomes set (IOFS = 1). Devices may vary from
one to the next and may take as long as 60 ms to
become stable.

Work around
Implement the following software delay shown in
Example 1 after an INTOSC frequency has been
enabled and before any frequency dependent appli-
cation code is executed. This routine will delay
application execution approximately 2K-150K T
(instruction cycles are dependent upon the INTOSC
frequency) to ensure a stable INTOSC frequency.

All date codes.
and a switch to an INTOSC frequency is
executed via modification of the IRCF bits.
This issue applies to TSL and non-TSL
devices.
