18.2.1
Because the OSCCON register allows clock switching
and clock scaling, a write to OSCCON is intentionally
made difficult. To write to the OSCCON low byte, this
exact sequence must be executed without any other
instructions in between:
• Byte Write “46h” to OSCCON low
• Byte Write “57h” to OSCCON low
• Byte Write is allowed for one instruction cycle
To write to the OSCCON high byte, this exact
sequence must be executed without any other instruc-
tions in between:
• Byte Write “78h” to OSCCON high
• Byte Write “9Ah” to OSCCON high
• Byte Write is allowed for one instruction cycle

quency of 480MHz (high-range FRC option for
industrial temperature parts with PLL and TUN<3:0> =
0111 bit settings). This signal is used by the Power
Supply PWM module, and is 32 times the input PLL fre-
quency.

Assuming the high-range FRC option is selected on an
industrial temperature rated part, the 480 MHz PLL
clock signal is divided by 2, providing a 240 MHz signal,
which drives the ADC Module. The same 480 MHz sig-
nal is also divided by 8 to produce the 60 MHz signal,
which is one of the inputs to the F
other input to this multiplexer is the FOSC input clock
source (either the Primary Oscillator or the FRC)
divided by 2. When the PLL is enabled, F
When the PLL is disabled, F
This method derives the 480 MHz clock:
• FRC Clock with high-range Option and TUN<3:0>
• PLL enabled
• PWM clock = 15 x 32 = 480 MHz
• F
If the PLL is disabled,
• FRC Clock (with high-range Option and
