21.2.4
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 21-3.
TABLE 21-3:
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rescinded.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.
21.2.5
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.
Using the x4, x8 and x16 PLL options, higher
operational frequencies can be generated.
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’.
There are four tuning bits (TUN<3:0>) for the FRC
oscillator in the OSCCON register. These tuning bits
allow the FRC oscillator frequency to be adjusted as
close to 8 MHz as possible, depending on the device
operating conditions. The FRC oscillator frequency has
been calibrated during factory testing. Table 21-4
describes the adjustment range of the TUN<3:0> bits.

21.2.6
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.
