8.1.3
The primary oscillator and internal FRC oscillator can
optionally use an on-chip PLL to obtain higher speeds
of operation. The PLL provides significant flexibility in
selecting the device operating speed. A block diagram
of the PLL is shown in Figure 8-2.
The output of the primary oscillator or FRC, denoted as
‘F
... or 33 before being provided to the PLL’s Voltage
Controlled Oscillator (VCO). The input to the VCO must
be selected in the range of 0.8 MHz to 8 MHz. The
prescale
PLLPRE<4:0> bits (CLKDIV<4:0>).
The PLL Feedback Divisor, selected using the
PLLDIV<8:0> bits (PLLFBD<8:0>), provides a factor, ‘M’,
by which the input to the VCO is multiplied. This factor
must be selected such that the resulting VCO output
frequency is in the range of 100 MHz to 200 MHz.
The VCO output is further divided by a postscale factor,
‘N2’. This factor is selected using the PLLPOST<1:0>
bits (CLKDIV<7:6>). ‘N2’ can be either 2, 4, or 8, and
must be selected such that the PLL output frequency
(F
generates device operating speeds of 6.25-40 MIPS.

The auxiliary clock generation is used for a peripherals
that need to operate at a frequency unrelated to the
system clock such as a PWM or ADC.
The primary oscillator and internal FRC oscillator
sources can be used with an auxiliary PLL to obtain the
auxiliary clock. The auxiliary PLL has a fixed 16x
multiplication factor.

For example, suppose a 10 MHz crystal is being used
with the selected oscillator mode of XT with PLL (see
Equation 8-3).
• If PLLPRE<4:0> = 0, then N1 = 2. This yields a
• If PLLDIV<8:0> = 0x1E, then M = 32. This yields a

The reference clock output logic provides the user with
the ability to output a clock signal based on the system
clock or the crystal oscillator on a device pin. The user
application can specify a wide range of clock scaling
prior to outputting the reference clock.
