Internal Precision Oscillator
PS022827-1212
Operation
The internal precision oscillator (IPO) is designed for use without external components.
You can either manually trim the oscillator for a nonstandard frequency or use the auto-
matic factory-trimmed version to achieve a 5.53 MHz frequency. IPO features include:
•
•
•
•
An 8-bit trimming register, incorporated into the design, compensates for absolute varia-
tion of oscillator frequency. Once trimmed the oscillator frequency is stable and does not
require subsequent calibration. Trimming is performed during manufacturing and is not
necessary for you to repeat unless a frequency other than 5.53 MHz (fast mode) or
32.8 kHz (slow mode) is required. This trimming is done at +30ºC and a supply voltage of
3.3 V, so accuracy of this operating point is optimal.
If not used, the IPO can be disabled by the Oscillator Control Register (see the
Control Register Definitions section on page
By default, the oscillator frequency is set by the factory trim value stored in the write-pro-
tected Flash information page. However, the user code can override these trim values as
described in the
