For timing insensitive applications, the “RC” and “RCIO”
device options offer additional cost savings. The RC
oscillator frequency is a function of the supply voltage,
the resistor (R

frequency will vary from unit to unit due to normal
ence in lead frame capacitance between package types
will also affect the oscillation frequency, especially for
low C
account variation due to tolerance of external R and C
components used. Figure 2-2 shows how the RC
In the RC Oscillator mode, the oscillator frequency
divided by 4 is available on the OSC2 pin. This signal
may be used for test purposes or to synchronize other
logic.
FIGURE 2-2:
The RCIO Oscillator mode functions like the RC mode,
except that the OSC2 pin becomes an additional
general purpose I/O pin. The I/O pin becomes bit 6 of
PORTA (RA6).
