20.2.2
In order to ensure that a crystal oscillator (or ceramic
resonator) has started and stabilized, an Oscillator
Start-up Timer is included. It is a simple 10-bit counter
that counts 1024 T
oscillator clock to the rest of the system. The time-out
period is designated as T
every time the oscillator has to restart (i.e., on POR,
BOR and wake-up from Sleep). The Oscillator Start-up
Timer is applied to the LP, XT, XTL, and HS Oscillator
modes (upon wake-up from Sleep, POR and BOR) for
the primary oscillator.
20.2.3
Enabling the LP oscillator is controlled with two
elements:
1.
2.
The LP oscillator is ON (even during Sleep mode) if
LPOSCEN = 1. The LP oscillator is the device clock if:
• COSC<2:0> = 000 (LP selected as main oscillator)
• LPOSCEN = 1
Keeping the LP oscillator ON at all times allows for a
fast switch to the 32 kHz system clock for lower power
operation. Returning to the faster main oscillator will
still require a start-up time.
20.2.4
The PLL multiplies the clock which is generated by the
primary oscillator. The PLL is selectable to have either
gains of x4, x8 and x16. Input and output frequency
ranges are summarized in Table 20-3.
TABLE 20-3:
The PLL features a lock output, which is asserted when
the PLL enters a phase locked state. Should the loop
fall out of lock (e.g., due to noise), the lock signal will be
rescinded. The state of this signal is reflected in the
read-only LOCK bit in the OSCCON register.

20.2.5
The FRC oscillator is a fast (7.37 MHz ±2% nominal)
internal RC oscillator. This oscillator is intended to
provide reasonable device operating speeds without
the use of an external crystal, ceramic resonator or RC
network. The FRC oscillator can be used with the PLL
to obtain higher clock frequencies.
The dsPIC30F operates from the FRC oscillator
whenever the current oscillator selection control bits in
the OSCCON register (OSCCON<14:12>) are set to
‘001’.
The 6-bit field specified by TUN<4:0> (OSCTUN<4:0>)
allows the user to tune the internal fast RC oscillator
(nominal 7.37 MHz). The user can tune the FRC
oscillator within a range of +12.6% (930 kHz) and -13%
(960
factory-calibrated setting, see Table 20-4.
If OSCCON<14:12> are set to ‘111’ and FPR<4:0> are
set to ‘00101’, ‘00110’ or ‘00111’, then a PLL
multiplier of 4, 8 or 16 (respectively) is applied.
