WebThe HSI clock can be used also to clock the USART, I2C and CEC peripherals. (#) HSI14 (high-speed internal for ADC), 14 MHz factory-trimmed RC used to clock the ADC peripheral. (#) LSI (low-speed internal), 40 KHz low consumption RC used as IWDG and/or RTC clock source. The most effective way to get the clock signal to every part of a chip that needs it, with the lowest skew, is a metal grid. In a large microprocessor, the power used to drive the clock signal can be over 30% of the total power used by the entire chip. The whole structure with the gates at the ends and all amplifiers in between have to be loaded and unloaded every cycle. To save energy, clock gating temporarily shuts off part of the tree.

WebRS-232 signals usually range between -13V and 13V, though the spec allows for anything from +/- 3V to +/- 25V. On these signals a low voltage (-5V, -13V, etc.) indicates either the idle line, a stop bit, or a data bit of value 1. A high RS-232 signal means either a start bit, or a 0-value data bit. That's kind of the opposite of TTL serial. Web(#) LSE (low-speed external), 32 KHz oscillator used as RTC clock source. LSE can be used also to clock the USART and CEC peripherals.
