MICROCONTROLLER WITH FIRMWARE SELECTABLE OSCILLATOR TRIMMING |
| 摘要 |
<p>A microcontroller circuit (10) includes an oscillator (14) receiving frequency trimming data (28) from a memory (16) under control of a microcontroller logic (12). The microcontroller logic (12) permits a user to alter the trimming data and to select through an oscillator logic (20) either the oscillator (14) or an external oscillator source (34) as a system clock (32).</p> |
