Legend:
y = Value set from Configuration bits on POR
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 15
Unimplemented: Read as ‘0’
bit 14-12
COSC<2:0>: Current Oscillator Selection bits (read-only)
000
= Fast RC oscillator (FRC)
001
= Fast RC oscillator (FRC) with PLL
010
= Primary oscillator (XT, HS, EC)
011
= Primary oscillator (XT, HS, EC) with PLL
100
= Secondary oscillator (SOSC)
101
= Low-Power RC oscillator (LPRC)
110
= Fast RC oscillator (FRC) with Divide-by-16
111
= Fast RC oscillator (FRC) with Divide-by-n

CLKLOCK: Clock Lock Enable bit
1
= If (FCKSM1 = 1), then clock and PLL configurations are locked.
If (FCKSM1 = 0), then clock and PLL configurations may be modified.
0
= Clock and PLL selections are not locked, configurations may be modified
bit 6
Unimplemented: Read as ‘0’
bit 5
LOCK: PLL Lock Status bit (read-only)
1
= Indicates that PLL is in lock, or PLL start-up timer is satisfied
0
= Indicates that PLL is out of lock, start-up timer is in progress or PLL is disabled
bit 4
Unimplemented: Read as ‘0’
bit 3
CF: Clock Fail Detect bit (read/clear by application)
1
= FSCM has detected clock failure
0
= FSCM has not detected clock failure
