Oscillator Control Registers
The
oscillators
are
controlled
with
two
SFRs,
OSCCON and OSCTUN and one Configuration
register, FOSC.
Note:
The description of the OSCCON and
OSCTUN SFRs, as well as the FOSC
Configuration register provided in this
section
are
applicable
only
to
the
dsPIC30F3014
and
dsPIC30F4013
devices in the dsPIC30F product family.

Legend:
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 Group Selection bits (read-only)
111
= PLL oscillator; PLL source selected by FPR<4:0> bits
011
= External oscillator; OSC1/OSC2 pins; external oscillator configuration selected by FPR<4:0>
bits
010
= LPRC internal low-power RC
001
= FRC internal fast RC
000
= LP crystal oscillator; SOSCI/SOSCO pins
Set to FOS<2:0> values on POR or BOR. Loaded with NOSC<2:0> at the completion of a successful
clock switch. Set to FRC value when FSCM detects a failure and switches clock to FRC.
