摘要: A standby control circuit for an integrated circuit module includes a first control circuit that is responsive, in a normal operating mode of the integrated circuit module, to an asynchronous standby signal indicating a standby mode entry event to output a standby mode signal synchronous with a primary clock signal to indicate a standby operating mode of the integrated circuit module. The standby control circuit also includes a second control circuit which is responsive, in a reduced power mode of the integrated circuit module, to the asynchronous standby signal indicating the standby mode entry event to control the first control circuit to output the standby mode signal synchronous with a secondary clock signal to indicate the standby operating mode.

摘要: A safety device with an error indication function includes at least one ERROR pad configured between the error indication function and at least one normal function, and a set of multiplexers connected to the ERROR pad. The safety device further includes an error indication block and a functional block multiplexed by the set of multiplexers. The error indication block includes a fault collection and control unit for collecting and providing error occurrence information to the ERROR pad, and an ERROR pad select control register for storing ERROR pad selection and configuration information to control select inputs of the first set of multiplexers and provide the ERROR pad configuration information to the ERROR pad.

摘要: A programming interface and method of operating a programming interface use a system clock input, an asynchronous reset input, and an interface control input. The method selectively controls multiplexed coupling of a source register to a destination register and the destination register to a buffer register. The multiplexed coupling of the destination register to the buffer register reduces the possibility of the buffer register being corrupted when an asynchronous reset signal is applied to the programming interface. Problems associated with meta-stable asynchronous crossing paths in asynchronous reset programming systems are therefore alleviated.
