HTS: HFINTOSC (High Frequency – 8 MHz to 125 kHz) Status bit
1 = HFINTOSC is stable

Configuration Word (CONFIG) of the device. The value of the OSTS bit will be ‘0’
on a device Power-on Reset (POR) or any automatic clock switch, which may occur
from Two-Speed Start-up or Fail-Safe Clock Monitor, if the following conditions are
true:
OSTS = 0 if:
FOSC<2:0> = 000 (LP) or 001 (XT) or 010 (HS)
and
IESO = 1 or FSCM = 1
(IESO will be enabled automatically if FSCM is enabled)
If any of the above conditions are not met, the value of the OSTS bit will be ‘1’ on
a device POR. See Section 3.6 “Two-Speed Clock Start-up Mode” and
Section 3.7 “Fail-Safe Clock Monitor” for more details.
