5.7.3.5 Internal Oscillators
To reduce production board costs and application development time, all F2807x devices contain two
independent internal oscillators, referred to as INTOSC1 and INTOSC2. By default, both oscillators are
enabled at power up. INTOSC2 is set as the source for the system reference clock (OSCCLK) and
INTOSC1 is set as the backup clock source. INTOSC1 can also be manually configured as the system
reference clock (OSCCLK). Table 5-18 provides the electrical characteristics of the internal oscillators to
determine if this module meets the clocking requirements of the application.
Table 5-18 provides the electrical characteristics of the two internal oscillators.
