Note 1:
IDLEN
R/W-0
Depends on the state of the IESO Configuration bit.
IDLEN: Idle Enable bit
1 = Device enters Idle mode on SLEEP instruction
0 = Device enters Sleep mode on SLEEP instruction
Unimplemented: Read as ‘0’
OSTS: Oscillator Start-up Time-out Status bit
1 = Oscillator Start-up Timer time-out has expired; primary oscillator is running
0 = Oscillator Start-up Timer time-out is running; primary oscillator is not ready
Unimplemented: Read as ‘0’
