T1OSCR
T1OSCR: Timer1 Oscillator Ready bit
If T1OSCEN = 1:
1 = Timer1 oscillator is ready
0 = Timer1 oscillator is not ready
If T1OSCEN = 0:
1 = Timer1 clock source is always ready
Unimplemented: Read as ‘0’
OSTS: Oscillator Start-up Time-out Status bit
1 = Running from the external clock source (EC)
0 = Running from an internal oscillator (FOSC<1:0> = 00)
HFIOFR: High-Frequency Internal Oscillator Ready bit
1 = HFINTOSC is ready
0 = HFINTOSC is not ready
Unimplemented: Read as ‘0’
LFIOFR: Low-Frequency Internal Oscillator Ready bit
1 = LFINTOSC is ready
0 = LFINTOSC is not ready
HFIOFS: High-Frequency Internal Oscillator Stable bit
1 = HFINTOSC 16 MHz oscillator is stable and is driving the INTOSC
0 = HFINTOSC 16 MHz oscillator is not stable, the Start-up Oscillator is driving INTOSC
