8.2
8.2.1
The PIC16F526 device can be operated in up to six
different oscillator modes. The user can program up to
three Configuration bits (FOSC<2:0>). To select one of
these modes:
• LP:
• XT:
• HS:
• INTRC: Internal 4/8 MHz Oscillator
• EXTRC: External Resistor/Capacitor
• EC:
8.2.2
In HS, XT or LP modes, a crystal or ceramic resonator
is connected to the RB5/OSC1/CLKIN and RB4/OSC2/
CLKOUT pins to establish oscillation (Figure 8-1). The
PIC16F526 oscillator designs require the use of a
parallel cut crystal. Use of a series cut crystal may give
a frequency out of the crystal manufacturers
specifications. When in HS, XT or LP modes, the
device can have an external clock source drive the
RB5/OSC1/CLKIN pin (Figure 8-2). In this mode, the
output drive levels on the OSC2 pin are very weak. If
the part is used in this fashion, then 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 (HS, XT or LP).
