If the IRCF<2:0> bits select 31 kHz, the LTS bit will be set after the INTRC is stable. If the IRCF<2:0> bits
select 125 kHz to 8 MHz, the HTS bit will be set after the INTOSC is stable.

or
The INTOSC oscillator
frequency is dependent
upon the IRCF bits.
During the 1024 clocks,
program execution is
clocked from the secondary
oscillator until the
primary oscillator becomes
stable.
When a Reset occurs, there
is no clock transition
sequence.
Instruction execution and/or
peripheral operation is
suspended unless
Two-speed Start-up or
Fail-Safe Clock Monitor is
enabled, after which the
INTOSC will act as the sys-
tem clock until the OST
timer has expired.
