bit 3

OSTS: Oscillator Start-up Time-out Status bit

= Device is running from the external system clock defined by FOSC<2:0>

= Device is running from the internal system clock (HFINTOSC or LFINTOSC)

bit 2

HTS: HFINTOSC (High Frequency – 8 MHz to 125 kHz) Status bit

=HFINTOSC is stable

= HFINTOSC is not stable

bit 1

LTS: LFINTOSC (Low Frequency – 31 kHz) Stable bit

= LFINTOSC is stable

= LFINTOSC is not stable

bit 0

SCS: System Clock Select bit

= Internal oscillator is used for system clock

= Clock source defined by FOSC<2:0>

Note 1: Bit resets to ‘0’ with Two-Speed Start-up and LP, XT or HS selected as the Oscillator

mode or Fail-Safe mode is enabled.

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

= Bit is unknown
