bit 0

Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

‘1’ = Bit is set

U = Unimplemented bit, read as ‘0’

‘0’ = Bit is cleared

x = Bit is unknown

bit 7

bit 6-4

bit 3

bit 2

bit 1-0

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)

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’

SCS1:SCS0: System Clock Select bits

1x = Internal oscillator

01 = Timer1 oscillator

00 = Primary oscillator

Note 1: Depends on the state of the IESO Configuration bit.
