    Abstract: Peripheral functions of an integrated circuit device may be pooled and dynamically mapped to available external input-output connections of the integrated circuit device by using a set of configuration registers. To provide system robustness, the configuration registers may implement various levels of write protection, error correction and monitoring circuitry. One or more peripheral output functions may be mapped to one or more external output connections. Not more than one output function may be active at the same time on the same output connection. Outputs and inputs may be mapped to the same external input-output connection with or without the output being controllable for placement into an inactive state, e.g., high impedance or open collector. When the input is required to receive external data over the external input-output connection, the output may be placed into the inactive state.

    IPC: H03K7/08

    Abstract: A pulse width modulation (PWM) generator having asynchronous updating of its PWM duty cycle and/or period values allows immediate correction for the new PWM duty cycle and/or period values instead of waiting until the end of a PWM period to accept the new duty cycle and/or period values. This reduces the latency in a control loop when responding to changing system status, e.g., changes in PWM duty cycle. Also the PWM duty cycle is prevented from "running away" (e.g., missing a PWM cycle) if the PWM duty cycle timer/counter has advanced beyond an updated duty-cycle maximum value.

    Abstract translation: 通过使用一组配置寄存器，集成电路设备的外围功能可以被集合并且动态地映射到集成电路设备的可用的外部输入 - 输出连接。 为了提供系统的鲁棒性，配置寄存器可以实现各种级别的写保护，纠错和监视电路。 一个或多个外围输出功能可以映射到一个或多个外部输出连接。 在同一输出连接上，同一输出功能可能同时处于活动状态。 输出和输入可以被映射到相同的外部输入 - 输出连接，具有或不具有可控制的输出以放置到非活动状态，例如高阻抗或开路集电极。 当输入需要通过外部输入 - 输出连接接收外部数据时，输出可能被置于非活动状态。

    Abstract translation: 具有其PWM占空比和/或周期值的异步更新的脉宽调制（PWM）发生器允许立即校正新的PWM占空比和/或周期值，而不是等待直到PWM周期结束才接受新的占空比 周期和/或周期值。 当响应改变的系统状态时，这减少了控制回路中的等待时间，例如，PWM占空比的变化。 而且，如果PWM占空比计时器/计数器超前于更新的占空比最大值，则PWM占空比被防止“逃跑”（例如，丢失PWM周期）。
