8.2
8.2.1
The PIC12F519 device can be operated in up to four
different oscillator modes. The user can program using
the Configuration bits (FOSC<1:0>), to select one of
these modes:
• LP:
• XT:
• INTRC: Internal 4 MHz or 8 MHz Oscillator
• EXTRC: External Resistor/Capacitor
8.2.2
In XT or LP modes, a crystal or ceramic resonator is
connected
(GP4)/OSC2 pins to establish oscillation (Figure 8-1).
The PIC12F519 oscillator designs require the use of a
parallel cut crystal. Use of a series cut crystal may give a
frequency
specifications. When in XT or LP modes, the device can
have
(GP5)/OSC1/CLKIN pin (Figure 8-2). When the part is
used in this fashion, the output drive levels on the OSC2
pin are very weak. This pin should be left open and
unloaded. Also when using this mode, the external clock
should observe the frequency limits for the clock mode
chosen (XT or LP).
