19.2.3
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<1:0> = 00 (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
19.2.4
The PLL multiplies the clock which is generated by the
primary oscillator or Fast RC oscillator. The PLL is
selectable to have either gains of x4, x8, and x16. Input
and output frequency ranges are summarized in
Table 19-3.
TABLE 19-3:
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rescinded.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.
19.2.5
The FRC oscillator is a fast (8 MHz 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 dsPIC30F operates from the FRC oscillator when-
ever the current oscillator selection control bits in the
OSCCON register (OSCCON<13:12>) are set to ‘01’.
The four bit field specified by TUN<3:0> (OSCON
<15:14> and OSCON<11:10>) allows the user to tune
the internal fast RC oscillator (nominal 8.0 MHz). The
user can tune the FRC oscillator within a range of
+5.25% (420 kHz) and -6.0% (480 kHz) in steps of
0.75% around the factory-calibrated setting, see
Table 19-4.

TABLE 19-4:
19.2.6
The LPRC oscillator is a component of the Watchdog
Timer (WDT) and oscillates at a nominal frequency of
512 kHz. The LPRC oscillator is the clock source for
the Power-up Timer (PWRT) circuit, WDT, and clock
monitor circuits. It may also be used to provide a low
frequency clock source option for applications where
power consumption is critical and timing accuracy is
not required
The LPRC oscillator is always enabled at a Power-on
Reset because it is the clock source for the PWRT.
After the PWRT expires, the LPRC oscillator will remain
on if one of the following is true:
• The Fail-Safe Clock Monitor is enabled
• The WDT is enabled
• The LPRC oscillator is selected as the system
If one of the above conditions is not true, the LPRC will
shut-off after the PWRT expires.
