21.2.3
Enabling the LP oscillator is controlled with two
elements:
• Current oscillator group bits, COSC<1:0>
• LPOSCEN bit (OSCCON<1>)
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 osc.) and
• 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 still
requires a start-up time.
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 or x16. Input and output frequency
ranges are summarized in
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 is
rescinded.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 (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. 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 (COSC<1:0>)
control
(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 7.37 MHz as possible, depending on the
device operating conditions. The FRC oscillator
frequency has been calibrated during factory testing.

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 POR
because it is the clock source for the PWRT. After the
PWRT expires, the LPRC oscillator remains 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
shuts off after the PWRT expires.
