OSCSTAT REGISTER
T1OSCR: Timer1 Oscillator Ready bit
If the Timer1 oscillator is enabled (T1OSCEN = 1)
else Timer1 oscillator is disabled - clock source is T1CKI
PLLR 4x PLL Ready bit
1 = 4x PLL is ready and can be switched to
0 = 4x PLL oscillator is not ready
OSTS: Oscillator Start-up Time-out Status bit
1 = Device running from the clock defined by FOSC<3:0> of the CONFIG1 register
0 = Device running from the internal oscillator (HFINTOSC, MFINTOSC or LFINTOSC)
HFIOFR: High Frequency Internal Oscillator Ready bit
1 = 16 MHz Internal Oscillator (HFINTOSC) is ready and can be switched to
0 = 16 MHz Internal Oscillator (HFINTOSC) is not ready
HFIOFL: High Frequency Internal Oscillator Status Locked bit (2% Stable)
1 = 16 MHz Internal Oscillator (HFINTOSC) is in lock
0 = 16 MHz Internal Oscillator (HFINTOSC) has not yet locked
MFIOFR: Medium Frequency Internal Oscillator (500 kHz HFINTOSC Output) Ready bit
1 = 500 kHz Internal Oscillator (MFINTOSC) is ready and can be switched to
0 = 500 kHz Internal Oscillator (MFINTOSC) is not ready
LFIOFR: Low Frequency Internal Oscillator Ready bit
1 = 31 kHz Internal Oscillator (LFINTOSC) is ready and can be switched to
0 = 31 kHz Internal Oscillator (LFINTOSC) is not ready
HFIOFS: High Frequency Internal Oscillator Stable bit (0.5% Stable)
1 = 16 MHz Internal Oscillator (HFINTOSC) is in communications stable
0 = 16 MHz Internal Oscillator (HFINTOSC) is not yet communications stable
R-0/q
PLLR
1 = Timer1 oscillator is ready and can be switched to
0 = Timer1 oscillator is not ready
1 = Timer1 oscillator is always ready
