PIC16HV540
7.2
7.2.1
The PIC16HV540 can be operated in four different
oscillator modes. The user can program two configura-
tion bits (FOSC1:FOSC0) to select one of these four
modes:
• LP:
• XT:
• HS:
• RC:
7.2.2
In XT, LP or HS modes, a crystal or ceramic resonator
is connected to the OSC1/CLKIN and OSC2/CLKOUT
pins
PIC16HV540 oscillator design requires the use of a
parallel cut crystal. Use of a series cut crystal may give
a frequency out of the crystal manufacturers specifica-
tions. When in XT, LP or HS modes, the device can
have an external clock source drive the OSC1/CLKIN
pin (Figure 7-2).

Rs may be required in HS mode as well as
XT mode to avoid overdriving crystals with
low drive level specification. Since each
crystal has its own characteristics, the user
should consult the crystal manufacturer for
appropriate values of external components.
