摘要： The invention provides an interrupt handling system to process a generated interrupt. At least one input is arranged to provide a predetermined active level, with a detection circuit associated with the input which is selectively configurable to detect either the active level or an inactive level. An interrupt request message causes the detection circuit to be configured to detect the active level, so that an enable logic is caused to generate an interrupt. The invention provides an integrated circuit and a method of generating interrupts using the above system, and a consumer electronic device in the form of a set top box or DVD Read and/or Write device.

摘要： A card reader reads data stored on a card. A contact signal is produced whose state is indicative of the presence or absence of electrical contact between the card and the card reader. A high state indicates the presence of electrical contact and a low state indicates the absence of electrical contact. Upon insertion of the card into the card reader, vibrations and other mechanical perturbations of the card cause the state of the contact signal to fluctuate rapidly between high and low states. The state of the contact signal is periodically sampled for a predetermined period of time and the number of samples for which the contact signal was high are counted. If the number of high samples exceeds a threshold then stable electrical contact is deemed to have been established between the card and the card reader and a system reset is performed.
摘要翻译：读卡器读取存储在卡上的数据。产生接触信号，其状态指示卡和读卡器之间是否存在电接触。高电平表示存在电接触，低电位表示不存在电接触。在将卡插入读卡器时，卡的振动和其他机械扰动导致接触信号的状态在高状态和低状态之间迅速波动。接触信号的状态在预定的时间周期内被周期性地采样，并对接触信号为高的样本数进行计数。如果高样本数超过阈值，则认为在卡和读卡器之间建立稳定的电接触，并执行系统复位。
