Микроконтроллеры

Мгновенно проснется любой проц, если его клокать от RC Это ж только кварц долго разгоняется, а RC ничего такого не надо. И Тексас здесь никакой америки не открыл, просто умело выпятил и разрекламировал это MSP-шное свойство, пока остальные ушами хлопали. MAXQ UG стр 48 System Clock Control Register (CKCN) CKCN.6 (RGSL) Ring Oscillator Select. This bit selects the internal ring oscillator for system clock generation. When RGSL is set to 1, the internal ring oscillator (following the PMME, CD1:0 selected divide ratio) is immediately sourced as the system clock and the internal crystal amplifier is disabled (if allowed). When RGSL is cleared to 0, the internal ring oscillator (following the clock divide selection) will continue to serve as the system clock until the warm-up counter associated with the XT/RC clock selection has expired. At which point, that clock source (following the PMME, CD1:0 selected divide ratio) is sourced as the system clock. The RGSL bit is cleared to 0 on power-on reset only and is unaffected by other resets. If the given MAXQ device does not include an internal ring oscillator from which it can run, this bit can be used as a general-purpose read/write bit.
